Coverage-connectivity based fault tolerance procedure in wireless sensor networks

摘要: In this paper, we propose a new approach to ensure fault tolerance in wireless sensor networks (WSNs) while guaranteeing both coverage and connectivity the network. Hence after reviewing related works enumerating requirements that must be satisfied by our solution, present different mechanisms maintain network case of node failure. Our is proactive one sense it aims replace “up fail” before its defection. impossible replacement node, fast rerouting mechanism proposed forward traffic initially routed via node. Performance evaluation shows number nodes potentially eligible for depends on threshold about redundancy as well density metric. Moreover, show that, compared classical routing algorithm, reduces packet loss rate
