Abstract
A heterogeneous wireless sensor networks (HWSNs) consists of two or more types of nodes. The redundancy management of various wireless sensor networks uses multipath routing to answer user queries in the presence of defective and malicious nodes. The fixed method uses a novel probability model to analyze the best redundancy level in terms of path redundancy (mp) and source redundancy (ms), as well as the best interruption detection settings in terms of the number of voters (m) under which the lifetime of a heterogeneous wireless sensor network is maximized while satisfying the reliability, timeliness and security, In this paper we propose an efficient scheme to control multipath congestion so that the sink can get priority based throughput for heterogeneous data. We have used packet service ratio for detecting congestion as well as performed hop-by-hop multipath congestion control based on that metric. Finally, simulation results have demonstrated the effectiveness of our proposed approach.
