Middle Position Dynamic Energy Opportunistic Routing for Wireless Sensor Networks

Wireless Sensor Networks (WSN) are the networks in which many tiny sensor nodes are deployed in the targeted region to form networks. The sensor nodes collect the information about physical or chemical phenomenon and transfer this information towards the base station for further processing. To achieve a high throughput in unreliable wireless links, Opportunistic Routing (OR) collaborate all the sensor nodes in the path while forwarding the data packets. Opportunistic routing takes advantage of the broadcasting nature of WSN for multi-hop communication. In this paper, Middle Position Dynamic Energy Opportunistic Routing (MDOR) has been proposed for efficient multi-hop communication between a source and destination pair in WSN. MDOR uses dynamic energy consumption when a packet is transmitted between nodes. In wireless sensor networks, there is a trade-off between the End-to-End delay and Network´s Lifetime, when we use the concept of dynamic energy consumption. It is observed that the average End-to-End delay is more in Energy Efficient Opportunistic Routing (EEOR) protocol as compared to the Multi-hop Optimal position Opportunistic Routing (MOOR) protocol. But in case of dynamic energy consumption, the networks lifetime of an EEOR protocol is better. The proposed protocol has optimized the End-to-End delay and Network´s Lifetime with the use of dynamic energy consumption.
