This paper reviews the past efforts of solar assisted-single effect vapour absorption cooling system for buildings. Besides the review of the past theoretical and experimental investigations of solar absorption cooling systems, some new ideas were introduced to reduce heat transfer loss to generator and thus to increase COP to get effective cooling. An experimental setup of vapour absorption cooling system was designed, developed and constructed. In order to monitor and analyze the performance of the cooling system it is necessary to collect the operation parameters of the system. In this regard the technique of visual instruments and the characteristics of cooling system is combined using national instrument product LabVIEW. © 2013 IEEE. Source

Mobile ad hoc networks (MANET) are characterized by dynamic topology without any static infrastructure. Now a day's mobile devices are connected as a wireless node. Due to changes in topology and mobility in MANET, it is suitable to use in environment that need of on fly set-up. The design of energy efficient on-demand routing protocol is a very difficult task in mobile ad hoc networks. Ad hoc On-demand Distance Vector Routing Protocol (AODV) for manet were employed on the route discovery process to establish routes between two mobile nodes. The link break problem may be occurring by the nodes due to mobility in ad hoc routing protocol. In a network when nodes establishing the connection utilize more energy in route discovery process, then the node will be out of energy. In this paper, we proposed a novel method to Minimizing the Route Rediscovery Process based Protocol (MRRP) by scheming the RREQ packet to select the more stable route and reduce the link break. The proposed protocol has two schemes, Received Signal Strength(RSS) based to minimizing the route rediscover process and the optimization of flooding process, based on Time-to-Live (TTL) value, reducing route rediscovery process solution to accomplish the link failure. Simulation was done on ns-2.34 platform and compared with the original AODV. By verifying the results, it improves the effectiveness and network performance of Quality of Service (QoS). © 2005 - 2014 JATIT & LLS. All rights reserved. Source

Mobile ad hoc networks is a self organizing wireless networks for mobile devices. It does not require any fixed infrastructure due to no wired backbone. It is suitable to use in environment that have a need of on the fly set-up. Every host is a router and packet forwarder. Each node may be mobile, and topology changes frequently and unpredictably due to the arbitrary mobility of mobile nodes. This aspect leads to frequent path failure and route rebuilding. Routing protocol development depends on mobility management, efficient bandwidth and power usage which are critical in ad hoc networks. In this paper, personalized Ad hoc On demand Distance Vector (RAODV) algorithm to reduce the link break scheme for mobile ad hoc networks. This present approach reduces packet loss and finds optimized route by taking into consideration of bandwidth, delay which results by improvement of quality of service. The performance analysis and simulation are carried out to evaluate network performance using network simulator NS-2 based on the quantitative basic parameters like throughput, delay in term of number of nodes and various mobility rates. A simulation result was during the comparison of AODV protocol with RAODV the probability of link break has been decreases in RAODV considering when various pause times and increases number of nodes. © 2012 IEEE.

Providing efficient resource allocation in the grid computing is a major task. In this paper, a simple and proficient fuzzy based resource allocation algorithm is proposed that not only provides efficient allocation of resources but also ensures high utilization of the resources which are dynamic. The proposed technique constitutes of three different stages namely classification of grid resources, generation of fuzzy rules, and resource allocation based on those fuzzy rules. In the first stage, the grid resource is classified on the basis of dwelling time. In the second stage, the fuzzy rules are developed to allocate the resources to the particular job. In the third & final stage of the technique, the resources are allocated to the submitted jobs based on the generated fuzzy rules. The performance of the proposed algorithm is evaluated on the basis of utilization, failure rate and makespan, and is compared with conventional scheduling algorithms like First Come First Serve (FCFS), Round robin and Random. The results shows that the proposed fuzzy based resource allocation of resource and thereby improving the performance. © 2012 IEEE. Source

Mobile ad hoc networks (MANET) also as called auto configure network, in which mobile devices are connected as a wireless node. Due to changes in topology and mobility in MANET, it is suitable to use in environment that need of on fly set-up. The design of energy efficient cluster based on-demand routing protocol and to increasing the life time of node it is a very difficult task in mobile ad hoc networks. Ad hoc On-demand Distance Vector Routing Protocol (AODV) for MANET were employed on the route discovery process to establish routes between two mobile nodes. One of the most important issue is the link break occurred by the nodes due to mobility in ad hoc routing protocol. In a network when nodes establishing the connection between the nodes, they utilize more energy in route discovery process, then the node will be out of energy. In this paper, we proposed a new idea to Minimizing the Route Rediscovery Process based on cluster Techniques (CBMRRP) by scheming the source node RREQ packet to select the more stable route i.e. cluster head selection. The proposed protocol has two schemes, first one is the selection of cluster heads based on Received Signal Strength(RSS) to minimizing the route rediscover process and the route optimization of flooding process, based on Time-to-Live (TTL) value,and the second one is by reducing route rediscovery process solution to accomplish the link failure. The analytical experiment was done by both probability and correlation techniques and simulation was done on ns-2.34 platform and compared with the original AODV. By verifying the result, the effectiveness and network performance of Quality of Service (QoS) are improved. © 2014 Praise Worthy Prize S.r.l. - All rights reserved. Source
