Abstract
Wireless sensor networks (WSN) are constrained by the processing speed, storage capacity, collision avoidance and energy which they are fundamental aspects in the development of communication protocols, and in this context, most research projects in this area focus on the aspect of energy, and ignore some QoS supports also interesting and unexplored, such as bandwidth, response time, ... Sensor networks require features such as energy conservation, the ability of scalability, fault tolerance and adaptability to topology changes. Indirectly, a communications protocol that avoids collisions saves energy, since the need to retransmit a message is reduced. The access to the communication medium by time-division multiplexing (TDMA) is a reasonable technique to avoid collisions. This paper mainly focuses on improving Masri's [1] TDMA protocol in tree-based clustered wireless sensor network, where the density of the network at the user level is translated by the bandwidth at the network. We prove firstly that the used formulas in [1] is false, after that, simulations results prove the robustness of our formulas and show that our approach outperforms Masri's one.
