A Novel Algorithm for Mobility of Wireless Sensor Network
چکیده
WSNs-Wireless Sensor Networks comprises of small nodes with computation, sensing and wireless communications capabilities. Energy awareness is an essential design for WSNs and hence data broadcasting protocols, routing and power management isspecially designed to meet this requirement. However, the focus is mainly on the routing protocols which differ depending on the network design and application. A three-layer framework is being proposed in this paperwork for mobile data collection in wireless sensor networks. This includes cluster head layer, mobile collector (SenCar) layer, and sensor layer. These sencars are movable hence it can be any mobile object, robot or moving vehicle that works as a robust energy recharger for the mobile nodes which really need energy in the sensor networks. The sencar whose battery is below the threshold level will start to move towards the sensor node. Based on the data transmissions and the purpose of the network, the threshold for all the sensor nodes are set in advance. Sencars move from its base station and move from cluster to cluster in its defined path in a WSN (wireless sensor network). WSN (wireless sensor network) communicates with a large number of sensor nodes. The sensor identifies the memory limit, accessibility and mobility of storage. Data is circulated to all nodes in a geographic area (geocast) from a service area. Then the content based inquires all sensors that detected some specific activity in the past hour. This wireless sensor network uses AODV (Ad-hoc On Demand Distance Vector) routing algorithm and MIMO (Multi 1108 K. Sowarna Lakshmi and N. Srinivasan Input Multi Output) Sencar is a mobile node that is set in the base station to detect the data status from source to destination. The sencars also measure the fixed threshold and detects the nodes whose limit of information transmission
