Abstract
This paper is concerned with the formal modelling and simulative analysis of an energy-efficient MAC protocol for gossip-based wireless sensor networks. This protocol is a variant of classical slotted Aloha in which the number of active TDMA slots is dynamically changed depending on the number of neighbours of a node. We provide a formal model of this protocol, and analyse energy consumption under the signal-to-interference plus noise ratio (SINR) radio model. We propose an amendment of the distributed slotted Aloha protocol by a simple dynamic power assignment scheme, and show that this significantly reduces the energy consumption (30%) and speeds up the message transmission. © Springer-Verlag Berlin Heidelberg 2011.
