A Cross-Layer Congestion Control Algorithm Based on Traffic Reallocation in Wireless Sensor Network

Huaiyu Wen, Weidong Huo
Abstract—Congestion is an essential problem in Wireless Sensor Networks (WSNs). In this paper, we present a traffic allocation and reallocation algorithm based cross-layer. There are mainly two parts in this framework: Efficient COgestion Traffic Allocation (ECOTA), Efficient COgestion DEection and Mitigation (ECODEM). By measuring Round Time of Trip (RTT), current traffic and node minimum energy of all paths, some low energy consumptions and short delay paths will be selected to increase the success rate of data transmission. When the congestion happens to Sensor Network, the congested areas will be detected by methods of checking node buffer and cross-layer state, and then nodes can quickly recover from congested situations by diverting the traffic to the non-congested area. Simulation results show that the proposed algorithm compared with COTA+CODEM can improve the success rate of packet delivery, reduce the transmission delay of end to end and improve the overall performance of the network.

Index Terms—Congestion, cross-layer, traffic allocation, traffic reallocation, ECOTA, ECODEM.
