Based on game theory, a general mathematical model, named by TRG/CSMA (Two Rounds Game CSMA), is proposed. TRG/CSMA select τ (the sending data packet probability) as optimization variable, and build a model named by n-persons non-cooperative game with mixed strategy. In this article, as special example, the throughput and delay is selected as optimization object, plays a game among n nodes respectively,...
In a wireless sensor network (WSN), interesting events are reported to the sink by the sensors in a distributed manner. Applications running at the sink require certain reliability in terms of events per unit time to be able to run satisfactorily. Individual report from sensor nodes is not important, but collective reports from sensor nodes of a region of interest of an application are crucial. Thus,...
In this paper, an analytical model for the non beacon-enabled mode of the IEEE 802.15.4 medium access control (MAC) protocol is provided. A wireless sensor network (WSN) composed of nodes, which transmit data to a sink through direct links, is considered. Upon reception of a query from the sink, the nodes transmit their packets by using the carrier-sense multiple access with collision-avoidance algorithm...
