Improved mesh WSN support for a realistic mobility model

This paper considers a realistic mobility model for a military application scenario using a wireless mesh sensor network. Within this model, the sink moves at the network boundary joining and leaving the network for different periods of time. Although the IEEE 802.15.5 standard has portability support for peripheral nodes (leaf devices) and is officially recommended for use in wireless mesh sensor networks, it is shown here that it can´t support the new mobility model proposed in this paper. Two solutions are suggested and discussed, the waiting for the destination and following the destination concepts.
