Fuzzy based Cross Layer Feed Back Mechanism for Mobility Aware Load Balanced Routing in WSN

چکیده
Wireless Sensor Networks (WSNs) are made up of small nodes which have the ability to sense, compute and communicate wirelessly. Essential design issue in WSN routing is energy awareness as the sensors are energy constrained. Various routing, power management and data dissemination protocols designed for WSNs are available in the literature. Energy awareness and reliable data transmissions are handled in Medium Access Control (MAC) and Network layers. Decisions to achieve data reliability and energy efficiency trade-off were considered in layers. This study considers mobility, energy and link qualities to ward off poor link connectivity which reduce retransmissions and prolong WSN life. To achieve this, a fuzzy based cross layer protocol is proposed using an enhanced MAC protocol to provide better contention during mobility of the node and a network layer protocol based on link quality and mobility is proposed. Input to the fuzzy system is link quality and mobility. Output is decision for cluster head selection.
