Failsafe wireless sensor network using cooperative communication

Abstract

Wireless sensor networks (WSN) are extensively utilized in many important applications. It is very important that the data from wireless sensor nodes must successfully reach the main location apart from issues related to capacity, coverage and event of failure. In this paper we propose a failsafe wireless sensor network based on the burgeoning concept called cooperative communication. Here the sensor node transmits data to the base station through ZigBee module with the range of 30m. In case where the probabilities for direct communication between the base station and sensor node become unfeasible, two cooperative relay nodes participate for successful transmission of data from sensor node to base station and improve the quality of service in the network even if one of the relay nodes fails which reduces chances in data loss from the sensor node and increases the performance of the system. From experimentation of system for three different cases, successful reception of data at the base station in real-time was achieved through space diversity.
