Abstract
In wireless sensor network (WSN) the use of mobile sink collector has been attracting more attention in recent times. The sensor nodes in WSN have limited power supply, computational capability, and storage hence, the mobile sink collectors are more effective way of balancing energy expenditure among sensors. In this paper, we consider applications, where sensing data are generally collected at a low rate and are not so delay sensitive that it can be collected into fixed-length data packets and uploaded once in a while. We propose a mobile data collector, which moves to the vicinity of the sensor nodes to collect data. A mobile collector starts the data-gathering tour periodically from the static data sink, polls each sensor while traversing its transmission range, then directly collects data from the sensor in single-hop communications, and finally transports the data to the static sink. Since data packets are directly gathered without relays and collisions, the lifetime of sensors is expected to be enhanced. In this paper, we discuss The Mobile sink which finds a route to the sensor node by using spanning tree covering algorithm. Sensor location information is collected using greedy perimeter stateless routing. We also evaluated network performance parameters throughput, energy consumption, end to end delay and packet delivery ratio.
