A novel QoS adaptive Multipath routing protocol in wireless multimedia sensor network proposed in this paper minimizes loss rate, energy consumption and delay. We consider a cluster based architecture where inter cluster routing is performed based on a weighted cost function considering the parameters such as loss rate, residual energy and delay. Existing works on Multipath routing rarely consider losses and delay at the sink leading to energy degradation, involve unnecessary additional paths which cause high overhead. To overcome these issues, an incremental on demand Multipath routing protocol is employed to minimize routing overhead. The simulation results prove that the proposed protocol is efficient in terms of energy efficiency, delay and packet delivery ratio when compared to the single path routing. © 2012 IEEE. Source

In Wireless Multimedia Sensor Networks (WMSN), routing is essential to promote high data rate accommodation. During the query and data dissemination phases, optimal routing is a vital role since the multimedia content is conditional to strict QoS requirements. But the existing works on Multipath routing rarely consider losses and delay at the sink leading to energy degradation, involve unnecessary additional paths which cause high overhead. To overcome these issues, in this paper, we proposed an adaptive multi constraint Multipath routing protocol which minimizes loss rate, energy consumption and delay. We consider a cluster based architecture where inter cluster routing is performed based on a weighted cost function. The cost function is based on the parameters such as loss rate, residual energy and delay. In order to save energy, nodes which don't take part in routing are put to sleep mode. The simulation results prove that the proposed protocol is efficient in terms of energy efficiency, delay and packet delivery ratio when compared to the QoS aware routing from the literature. © 2012 IEEE.

Mobile Ad-hoc network (MANET) is an autonomous system of mobile nodes/devices connected by wireless links. These mobile nodes are free to move anywhere in the network without any centralized control. Multimedia applications are gaining great popularity in MANETs as these networked and portable devices are becoming more powerful and more multimedia enhanced. These type of applications define a new set of requirements in which they operate put together called as Quality of Service(QoS). Hence, it is desired to discover an optimal path including QoS parameters like delay, etc to enable better performance of multimedia applications. This paper focuses on improving route maintenance for QoS in MANETs. The ad-hoc on-demand distance vector (AODV) routing protocol is modified to provide QoS in terms of end-to-end delay and also aims to minimize the modifications to the protocol. © 2013 IEEE. Source

In this paper, We have developed a new energy efficient routing protocol called An Energy Efficient Reliable Routing Protocol for Wireless Sensor Networks (WSN) which is cluster based. Data aggregation is essentially used to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. Data aggregation protocols aims at eliminating redundant data transmission. Power consumption is an important aspect to be considered in the data aggregation which is a scarce resource and they are irreplaceable. In addition to power consumption, reliability is also of major concern in data aggregation. Initially we form clusters and a coordinator node (CN) is selected near the cluster in order to monitor the nodes in the cluster. The CN selects a cluster head (CH) in each cluster based upon the energy level and the distance to the CN. The packets sent by the sensor nodes are aggregated at the CH and transmitted to the CN. The CN measures the loss ratio and compares it with a threshold value of loss ratio. Depending upon this value, the forward node count is incremented or decremented and the cluster size is adaptively changed, ensuring reliability and balanced energy consumption. We have compared the new protocol with Low Energy Adaptive Clustering Hierarchy (LEACH) using NS-2, evaluated the protocol, the simulation results show that EERDAT outperforms the LEACH. © 2012 IEEE.

Data aggregation protocols aims at eliminating redundant data transmission. Power consumption is an important aspect to be considered in the data aggregation which is a scarce resource and they are irreplaceable.

Depending upon this value, the forward node count is incremented or decremented and the cluster size is adaptively changed, ensuring reliability and balanced energy consumption. We have compared the new protocol with Efficient Reliable Data collection (eRDC) using NS-2, evaluated the protocol by varying numbers of nodes. The result shows that EERDAT outperforms the eRDC. © 2012 IEEE. Source
