Abstract
Wireless Sensor Network (WSN) is a special type of communication medium through distributed sensor nodes. Popular wireless sensor nodes like ZigBee have splendid interoperability after IEEE 802.15.4 standardization in the domain of wireless personal area network (WPAN). ZigBee has another great feature mobility that makes the ZigBee network more versatile. The mobility feature of ZigBee mobile nodes has a greater impact on network performance than fixed nodes. This impact sometimes turns into more severe because of network structure and mobility model. This study mainly focuses on the performance analysis of the ZigBee mobile node under Random and Octagonal mobility management model with the Tree routing method. The Riverbed academic modeler is used to design, implement and simulate the ZigBee network under certain conditions. This study also presents a competitive performance analysis based on ZigBee mobile nodes transmitter and receiver characteristics under the observation of the mobility model. This indicates that Octagonal mobility model exhibits better performance than the Random mobility model. This study will constitute a new way for further designing and planning a reliable and efficient ZigBee network.
Highlights
Wireless Sensor Networks (WSNs) are highly integrated technologies comprising of sensors, microcontrollers and wireless networking capabilities which autonomously collect data and send data through a sink
Static sink based wireless sensor networks were deployed in the past but mobile sink has changed the direction in the research field
This study presents random and a unique octagonal structured ZigBee network to evaluate ZigBee mobile sink’s mobility feature
Summary
Wireless Sensor Networks (WSNs) are highly integrated technologies comprising of sensors, microcontrollers and wireless networking capabilities which autonomously collect data and send data through a sink. Nowadays, it is one of the most emerging research fields in the world. Several studies have been done on different performance analysis and enhancement of management approach for ZigBee mobile nodes [6] [7]. The study [6] describes ZigBee based wireless sensor networks mobile sink implementation in terms of various mobility strategies. The study [10] presented an enhanced approach for mobility management of end devices in ZigBee cluster tree network.
