A New Reliable and Energy Efficient Opportunistic Routing Protocol for Wireless Sensor Networks

the major research problem in WSN is to save energy in different operations of the network and increase the lifetime. Most of the energy of a node is consumed during routing process. This is because the environment in which the WSN is used is unstable in nature most of the time like in habitat monitoring, defense applications and industrial applications etc. Hence, there is a need of energy efficient routing protocols. Researchers have proposed protocols and algorithms for routing process in WSN. Traditional routing protocols do not work well with WSN because it is a constrained network. The routing protocols for WSN are classified into four different categories, data centric, hierarchical, location based and opportunistic routing protocols. Opportunistic routing protocols are efficient and reliable in the data delivery process because it utilizes the broadcasting nature of WSN. In this paper we have proposed an energy efficient opportunistic routing protocol which is able to increase the reliability and lifetime of the network. The proposed protocol also increase system throughput and system delay, and energy efficiency. The proposed protocol can be applied to static sensor networks to produce high performance.
