According to wireless sensor network (WSN) nodes have unstable performance and are easy to lose effectiveness, a WSN routing failure node verification method, NEVM (Node-Encoding Verification Method), based on node encoding is proposed. The method encodes failure route node with binary encoding and generates more verification path, then sends verification packages to each path and generates a sequence...
In wireless sensor network, all nodes are energy constrained and designing an energy efficient routing protocol is very important. Clustering routing protocol is a kind of energy efficient routing, while using a virtual backbone to organize the nodes and perform an efficient routing is also a feasible way.
Wireless sensor network is composed of hundreds of sensor nodes involving in limited energy, efficient and low-energy consuming routing algorithm is the crucial problem to the routing design. In this paper, the LEACH protocol, which is a typical clustering routing protocol, has been researched and improved based on energy, the new algorithm is different from the LEACH in the method of determining...
Recently, a new routing protocol notes as enhanced tree routing (ETR) has been designated for wireless sensor networks. However, when using the ETR to determine next-hop neighbor, only the reduced hops via them are employed, but the residual energies of one-hop neighbors are not considered. To overcome this flaw of ETR, we propose an improved ETR with energy awareness (ETREA) for sensor network. This...
Transmissions of large sized images can be a bottleneck for a wireless sensor network (WSN) due to its limited resources. Security can be another concern. This paper proposes a collaborative transmission scheme for image sensors to utilize inter-sensor correlations to decide the transmission and security sharing patterns based on the path diversities. Our proposed approach for secret image sharing...
