Wireless sensor networks (WSNs) usually build from huge number of randomly deployed sensor nodes in certain area. The sensors are mainly utilized to monitor physical and environmental conditions, gather information, process this data locally and transfer the sensed data back to the Base Station (BS). The main objective of this paper is to simulate, evaluate and observe the behavior of developed clustering...
The paper presents the criteria that affect the performance of network lifetime in Wireless Sensor Networks. In sensor networks the nodes can be organized into clusters for one hop energy-efficient data routing. This work focuses on adaptive clustering of sensor nodes where the role of cluster head changes among nodes. The nodes take turn to become cluster head based on one or several parameters such...
In this paper, we evaluate network performance of non-acknowledged packet transfer in relatively large IEEE 802.15.4 network. Network under consideration contains six interconnected IEEE 802.15.4 beacon enabled network clusters in triangular topology using slave-slave (SS) bridges with CSMA-CA access. We investigate the interactions among local nodes, local bridges and remote bridges. Simulation results...
