Abstract
This paper proposes and analyzes the performance of an efficient error control scheme for time sensitive applications on wireless sensor networks. The proposed scheme divides DCF into HDCF and LDCF without changing PCF, aiming at maximizing the successful retransmission of a packet that carries critical data. While channel estimation obviates the unnecessary polls to the node in channel error during PCF, two level DCF enables prioritized error recovery by making only the high priority packet be retransmitted via HDCF. A good chop value can distribute the retransmission to each period, maximizing recovered weight, or criticality as well as keeping low the possible loss of network throughput. The simulation results show that the proposed scheme can improve recovered weight by 8% while showing 97% successful transmission at maximum for the given simulation parameter.
