Energy Proficient Flooding Scheme Using Reduced Coverage Set Algorithm for Unreliable Links

Wireless sensor network is a spatially distributed node that is monitored by sensors and it transmits the measured information to sink node or base station. The prevalence of wireless sensor network is that it can cope up with the node failure, and also it has the maximum potential to manage the mobility of nodes. It is also easy to handle and it can withstand in a harsh environment. Flooding is the basic attempt in the wireless sensor network in order to disseminate the message to the entire network. Flooding concept helps in discovering location, route establishments, querying etc .Many protocols and applications rely on flooding in Wireless sensor network communication purposes. To achieve reliability and energy proficiency, it is essential to consider retransmission and rebroadcasting of the same message while flooding. In this paper, a novel forwarding scheme called Reduced Coverage Set is proposed that reduces the number of rebroadcast and retransmission opportunistically and thereby reducing energy consumption. Also to improve the performance of the network during link failure and packet loss a Better Link Choosing Scheme is proposed to select the better link. By comparing with traditional flooding algorithms, the proposed design shows an outstanding performance by reducing the redundant packet transmissions by 12%~30%, thereby increasing the network life time.
