Ultra-reliable and energy efficient wireless sensor networks

Abstract

Near instant link failure recovery and lower energy consumption can be achieved via the synergistic combination of Diversity and modified Triangular Network Coding (eDC-NC), an open-loop coding technique, in a wide variety of network architectures. In this paper, eDC-NC is applied to Wireless Sensor Networks (WSNs) to enable very rapid recovering from wireless link/node failures and provide low computational and energy cost, which are very important metrics for WSNs. It is shown that utilizing eDC-NC coding in WSNs can provide ultra-reliability with very rapid fault recovery, decrease energy consumption, and increase the network throughput for broadcasting applications.
