A New Multipath Protocol for Path Stability in Wireless Sensor Networks

摘要

Energy efficiency is a major issue in Wireless Sensor Networks. Due to path failure, sensor nodes consume high energy. So, the performance of the networks is totally degraded. To overcome this issue, we proposed New Adaptive Reporting Protocol (NARP). It attains both throughput and network connectivity while keeping the nodes moving in dynamic manner. The scheme consists of two phases. In fist phase, we proposed multipath routing to provide load balancing to improve the throughput. The proposed multipath contains the route discovery process and route maintenance process. During route selection, the minimum power consumption route is chosen to set the maximum power efficiency. In second phase, the path stability is determined to improve the network connectivity and reduce the packet losses. Here the sensor nodes are assigned with the constant codewords and different time slots. By using the extensive simulation results using the discrete event simulator, the proposed NARP achieves higher packet delivery ratio, network lifetime, less energy consumption, overhead and delay than the existing scheme GSTEB.
