The Primary concern in a Wireless Sensor Network is Energy consumption. The main problem in the network is when the data is sent from node to sink, the data will be lost due to polling point problem or low energy of node. Multi sencar technique is used to overcome polling point problem. In this paper, the tradeoff between energy saving and data gathering latency in mobile data gathering by trav...
Decrease in the time interval between the first node death and the last node death, due to the completion of their energy supply, is the main goal of load-balancing methods in Wireless Sensor Networks (WSN). This paper proposes a Load-Balancing Enhancement (LBE) method, in WSN. LBE method uses a mobile data collector to data gathering from sensor nodes. The mobile data collector can directly co...
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...
In this paper, we proposed a new data-gathering mechanism for large-scale wireless sensor networks by introducing mobility into the network. A mobile data collector, for convenience called an M-collector in this paper, could be a mobile robot or a vehicle equipped with a powerful transceiver and battery, working like a mobile base station and gathering data while moving through the field. An M-...
Energy consumption is a primary concern in the Wireless Sensor Network. This leads to pursue the maximum energy saving at sensor nodes, where a relay is used to transfer the data packet. This leads to the increase in the data gathering latency due to low moving velocity of the mobile collector. In this paper we study the tradeoff between energy saving and data gathering latency in mobile data g...
Energy consumption becomes a primary concern in a Wireless Sensor Network. Wireless sensor network (WSN) requires robust and energy efficient communication protocols to minimize the energy consumption as much as possible. We propose a polling-based mobile gathering approach and formulate it into an optimization problem, named bounded relay hop mobile data gathering (BRH-MDG). Specifically, a su...
In this paper, polling based mobile data gathering and the priority based data storage algorithm for wireless sensor networks (WSN) is proposed. Initially, the centralized algorithm places the polling points (PPs) on the shortest path. These polling points (PP) buffer locally aggregated data and upload the data to the mobile data collector when it arrives. Then, priority based data storage modu...
