Recent advances in wireless communication technologies have enabled the development of Wireless Sensor Networks (WSNs) that consist of low cost, power and small-size sensor nodes. ZigBee, an IEEE 802.15.4 based wireless sensor networks have been the promise of facilitating large-scale and real-time data processing in complex environments. Mobility management is a challenging task in the IEEE 80...

Wireless sensor network [1] generally consists of large number of sensor nodes. The wireless sensor network can be defined as large number of small sensing self powered nodes which gather the information from the geographical area and communicate in wireless fashion with the goal of handing their processed data to the base station. Due to the power restriction of sensor nodes, efficient routing...

Wireless Sensor Network (WSN) is a wireless network consisting of small nodes with sensing, computation, and wireless communications capabilities. The design of wireless sensor networks depends of many factors, such as transmission errors, network topology and power consumption. Many routing protocols, protocols for data transmission, are specifically designed for wireless sensor networks where...

With the emergence of cyber-physical systems, there has been a growing interest in network-connected devices.
