Abstract

Ensure data delivery and extend the network lifetime are challenges that must be addressed when it comes to deploy a WSN in outdoor harsh environment where it operates over unstable links. The instability of radio links may induce a connectivity that is time-varying even when nodes are not moving. For these dynamic topologies, resources allocated to the nodes must be adjusted to the local traffic conditions. Amongst the proposed solutions, schedule-based protocols achieve an energy efficiency as they allow nodes to sleep during their inactive periods. As the channel conditions are time-varying, and paths followed by the packets are changing, inducing an instability in the distribution of the traffic load over the network. This paper is dealing with the mastering of the size of the reception time slot of the next hop node. Our solution dynamically takes in consideration the local traffic load to resize the time slots. This adaptive solution is compared with the fixed-length window scheme, it obviously improves the performance of the WSN in terms of cycle length, idle listening and collision reduction, and achieves suitable data delivery ratio.
