Implementation of improved Robust Energy Efficient Routing protocol

Wireless Sensor Networks (WSN) enables fault tolerant monitoring and control of a variety of applications. The design of micropower wireless sensor systems has gained increasing importance for a variety of civil and military applications. Power is the major topic of concern in present embedded systems. Wireless sensor networks have sensor nodes, which is an embedded device equipped with cameras, microphones, and other sensors producing multimedia content, embedded into a single processor board which runs on batteries. Wireless sensor nodes must utilize the minimal possible energy while operating over a wide range of operating scenarios. Due to the large number of wireless sensor nodes that may be deployed and the long system lifetimes required, replacing the battery is not an option. The data transmission and reception between the wireless sensor nodes and the sink and source nodes contributes to major energy consumption, which needs to be handled with attention. In our paper we proposed an improved routing protocol to reduce the power consumption of the embedded node by reducing the computation overhead and data routing through less energy consuming route through sensor nodes of interest. The proposed routing protocol has been simulated and compared with existing routing protocols with Network Simulator Ns2, Which is open source software.
