posted on 2009-01-28, 14:22 authored by Fang Yao, Shuang-Hua YangWireless sensor networks (WSN) are designed to
collect and process sensory data from environments. Some
environments are dangerous or un-reachable to human
beings and it is difficult to replace sensor nodes when they are
out of battery or even destroyed, i.e. wireless sensor nodes are
in general prone to failure. This kind of characteristics
require WSN to detect whether or not its next destination is
still available (alive) and to maintain a transferring path if the
next destination in the route does not exist (dead). In the
normal state, nodes are in power-saving 'sleep' state. When a
route is created for some purpose, all nodes in this route will
be active and be ready to respond requests from its neighbors.
Our approach is to maintain the routing table up-to-date by
sending message from a last node to its next node and judging
whether the next node is alive according to the response. If
problems happen, node will self-organize and try to maintain
transferring.
