Forward Error Correction Techniques for Wireless Sensor Networks

Wireless sensor networks have been envisioned as one of most important technologies. The emerging advancements in the field of microelectronics and wireless communications have allowed the development and deployment of wireless sensor networks. Wireless sensor networks consist of many sensor nodes that range from hundreds to thousands depending on the phenomena being observed within an environment. These low-power small units are able of sensing, processing, and communicating with each other. They are widely deployed in different fields such as military, environment, health, and industry. Their applications range from battle field surveillance, to early earth quake and forest fire detection, to factories and highways monitoring. Sensor nodes are usually battery operated and deployed in harsh and unreachable environments making it impossible to replace their batteries. Consequently, the wireless sensor network is susceptible to failure due to the power depletion of some of its nodes. Therefore, a power constraint is identified as one of the most critical challenges in wireless sensor networks. In this work, we propose a novel approach to ECC in wireless sensor network. We introduce a modification to Reed-Solomon decoding algorithm which allows errors to occur in data without sacrificing the total integrity of the data. Additionally, we investigate the use of ECC with network coding cooperation and we propose an ECC coded partial network coding with cooperation.
