Wireless Sensor Node Performance Analysis Under Mac Protocol IEEE 802.15.4

Abstract

The long-term use of sensors while guaranteeing good performance is a major challenge for sensor networks. To address this issue, it’s important to have a good resources management policy. So it is necessary to find the main factors which affected the behaviour of each sensors inside the networks to. In this paper we proposed an enhanced analytical model of CSMA/CA 802.15.4 standard and we study the performance of the proposed model under the MAC parameters and the density of network to find the keys parameters that impacted the quality of services (QoS) of the network.
