摘要：Wireless sensor networks are an important for monitoring distributed remote environments. As one ofthe key technologies involved in WSNs, nodes fault detection is indispensable in most WSN applications. It is wellknown that the distributed fault detection scheme checks out the failed nodes by exchanging data and mutually testingamong neighbor nodes in this network, but the fault detection accuracy of a scheme would decrease rapidly when thenumber of neighbor nodes to be diagnosed is small and the node’s failure ratio is high. An improved scheme isproposed by defining new detection criteria. Simulation results demonstrate that the improved scheme performs well inthe above situation and can increase the fault detection accuracy greatly. Wireless sensor-actor networks, sensors probetheir surroundings and forward their data to actor nodes. Actors collaboratively respond to achieve predefinedapplication mission. Since actors have to coordinate their operation, it is necessary to maintain a strongly connectednetwork topology at all times. Moreover, the length of the inter-actor communication paths maybe constrained to meetlatency requirement. Cost Aware Secure Routing protocol to address these two conflicting issues through twoadjustable parameters: energy balance control and probabilistic based random walking. CASER has an excellentrouting performance in terms of energy balance and routing path distribution for routing path security. We alsoproposed a non uniform energy deployment scheme to maximize the sensor network lifetime. Our analysis andsimulation will showing that we can increase the lifetime and the number of messages that can be delivered under thenon-uniform energy deployment by more than four times. CASER has flexibility to support multiple routing. The mainobjective to have a network which gives assurance of packet delivery and give the node time to regain its so that it willbe able to carry further load Packets on the network. This can be done by using shortest path. Prior work relies onmaintaining multi hop neighbor lists and predetermines some criteria for the node’s involvement in the recovery. Multihop based schemes often impose high node repositioning overhead and the repaired inter actor topology using two hopschemes may differ significantly from its pre failure status.
