Precedence control scheme for WSNs

The heterogeneous wireless sensor network is currently finding the ways to handle the various issues of storage, communication, and computation. Due to limited resources available at sensor nodes, protocols need to be carefully designed to solve the current problems. While designing the prioritized transport layer protocol for multi-event, the several design issues are required to take into consideration cautiously. Therefore, this paper discusses the various issues of the prioritized transport protocol for heterogeneous wireless sensor networks like variable reliability, loss recovery, handling multi-events, congestion control, fairness, energy consumption, query response time, and many more in order to make efficient priority based transport protocol especially for heterogeneous wireless sensor network. The precedence control scheme achieves some improvements in throughput, packet delivery ratio as compared to non precedence control scheme.
