Energy efficiency and latency improving protocol for wireless sensor networks

Abstract

In delay sensitive applications of wireless sensor network, it is required to monitor the situation continuously with the sensors. The continuous monitoring operation results in more energy consumption of the sensor nodes. If the delay in data processing and it's communication from one node to other is more, then energy requirement may increase. In most of the situations, it is difficult to replace the battery of a sensor node, after the deployment of node in the network. The efficient energy management and low latency are the important issue in such applications as they affect the life of network. Many protocols are suggested by various researchers for energy efficient data process and minimum latency in sensor networks. There are limitations in existing protocols as they are particularly designed either for energy efficiency or minimum latency or for both. This paper presents the new protocol to overcome some of the existing protocol's limitations. In this paper, a concept of distance metric based routing protocol approach is explored, for `high energy efficiency' and `shortest path selection' for latency improvement. The proposed new protocol is `Dynamic Energy Efficient Latency Improving Protocol (DEELIP)'. The simulation results are compared with `AODV' routing protocol. It is observed that in proposed protocol; the overhead of the network traffic is reduced, resulting in improvement of energy efficiency and latency than existing routing protocols.
