An IPv6-Based Traffic Balancing Scheme for Multiple Mobile Data Collectors in Wireless Sensor Networks

The converge cast traffic pattern (many-to-one data communication) of wireless sensor networks leads to high load at nodes that are aggregating data. Therefore, we need to distribute the entire traffic load by deploying multiple data collectors and each node should select a collector node to access. Additionally, with the progress of IPv6-based wireless sensor networks, advantages of IPv6 protocols can be considered to address the above problem. In this paper, we propose an IPv6-based traffic balancing scheme for multiple mobile data collectors in wireless sensor networks, which can distribute the traffic load on multiple mobile data collectors based on IPv6 any cast and pseudo-mobility (IPv6APM). The scheme has the advantages of seamless compatibility with current protocol, higher scalability, short delay time, no topological constraint compared to other approaches. We also present our simulation work and discuss performance comparison between the scheme and other load balancing mechanisms. The results show that the scheme has very advanced performance and scalability.
