Wireless sensor network is commonly used to monitor certain region and to collect data for several applications. Normally, in wireless sensor network, data are routed in a multi-hop fashion towards a static sink. In this scenario, nodes closer to the sink become heavily involved in packet forwarding and their battery power is exhausted quickly. In this paper, an Infrastructure based Data Gather...

Recent research shows that significant energy can be saved by using mobile elements (ME)for data gathering in wireless sensor networks. The major drawback of this approach is the low movement speed of MEs which limits them to gather data from all sensor nodes with time constraints. This paper presents a data gathering algorithm called Minimum Mobile Elements Routing with Deadline (M2ERD). The g...

In the wireless sensor networks, resource constraints such as bandwidth and energy limitations, limited communication range, low storage and weak processing capacity motivate researchers to solving these problems. Presenting new algorithms such as efficient mobile agent based dada gathering methods would be a good solution for this case. Some of important advantages of mobile agent based data g...

Data gathering is a key operator for applications in wireless sensor networks; yet it is also a challenging problem in mobile sensor networks when considering that all nodes are mobile and the communications among them are opportunistic. This paper proposes an efficient data gathering scheme called ADG that adopts speedy mobile elements as the mobile data collector and takes advantage of the mo...

A mobile sensor network is a wireless network of sensor nodes that move arbitrarily. In this paper, we explore the use of a maximum stability spanning tree-based data gathering (Max.Stability-DG) algorithm and a minimum-distance spanning tree-based data gathering (MST-DG) algorithm for mobile sensor networks. We analyze the impact of these two algorithms on the node failure times and the result...
