PEER: Proximity-Based Energy-Efficient Routing Algorithm for Wireless Sensor Networks

With efficient routing, Wireless Sensor Networks (WSNs) can provide the continuous transmission with improved lifetime. Different routing protocols account for the different results over the WSNs. WSNs acquire special place in modern day network applications such as body area networks, home animations, cellular enhancement, etc. Especially, focusing on the home automation, a lot of routing algorithms and protocols have been proposed over the years that aim at enhancing the lifetime of such networks. Some of the popular algorithms include Relative Direction Based Sensor Routing (RDSR), Convention Routing (CR), Relative Identification and Direction-Based Sensor Routing (RIDSR), etc. These protocols focus over solving the routing loop problem along with improvement in lifetime of the overall network. However, the gains attained by these networks show a relatively less improvement. Thus, considering the similar problem of routing loop and a lifetime, an energy efficient routing algorithm developed on the backbone of the RIDSR is proposed. The proposed routing algorithm uses the proximity approach to find the appropriate set of nodes for transmission, thus, improving lifetime and resolving routing loop issues. The effectiveness of the proposed Proximity Based Energy Efficient Routing (PEER) is demonstrated in as gains attained in terms of improved lifetime, and energy consumption.
