Communication Protocols for Distributed Wireless Sensor Network based on Viterbi Algorithm.

Routing is one of the most important technologies in wireless sensor networks. The energy efficiency of the sensor network is realized by combining other technologies with routing protocols in this paper. First, through the analysis of the energy model of the clustering routing algorithm, the local signal to noise ratio (SNR) is used to purposefully select the nodes in the cluster to transmit data. In order to avoid the energy consumption of a large number of nodes to transmit data, a simple architecture is proposed to combine the distributed source code with the cluster routing protocol. The method uses the data on the cluster head as the edge information to decode the compressed information transmitted from the cluster nodes. The simulation result shows that the energy efficiency of the network can be achieved through this combination. [ABSTRACT FROM AUTHOR]
