This paper proposes a comprehensive routing protocol (CRP) based on the ant colony algorithm for the applications of Wireless Sensor Network (WSN). It is a protocol taking both the lifetime of network and the arrival rate of data packet into account. In CRP, multiple paths are found between source and destination, and sub-optimal paths are used occasionally referring to the probabilistic forwarding...
Routing is a key technique for wireless sensor networks (WSN). In order to improve the efficiency of routing in large-scale WSN, we propose Sink Routing Table (SRT) routing protocol, a routing protocol for WSN, in this paper. In SRT protocol, nodes aggregate data and use energy aware neighbor selection to route packets towards the target along an optimal path, each common node has no need to maintain...
This paper proposes a routing protocol for the applications of Wireless Sensor Network (WSN). It is a protocol based on the PEGASIS protocol but using an improved ant colony algorithm rather than the greedy algorithm to construct the chain. Compared with the original PEGASIS, this one, PEG-ant, can achieve a global optimization. It forms a chain that makes the path more even-distributed and the total...
In wireless sensor networks, proposed an energy efficient routing strategy based on ant colony algorithm. The algorithm combined residual energy of nodes, and accorded to transition probability to choose the next node. When ants passed a node, updated the path list and node information table .Through the node information table, nodes in the network are divided into ordinary nodes and aggregation nodes,...
Aiming at the shortage of LEACH protocol, a new routing protocol CDS-EBRP is proposed in this paper, CDS-EBRP fully takes account of the energy consumption of individual node and entire network, a rational transmission path from nodes of network to sink node is searched, Aiming at the network topology changes which are caused by the dead of cluster head nodes, the invalidation of cluster member nodes...
This paper considers a circular high-density WSNs, which is divided into several homogeneous sectors. For a sector, the route nodes transmit data to base station (BS) along the sides of the sector and the radio of nodes can cover all areas of target area. The paper presents an energy-balance solution to balance the energy consumption, by adjusting transmission range with quality coverage under a FSCTA...
In this paper, we propose GROUP, a grid-clustering routing protocol that provides scalable and efficient packet routing for large-scale wireless sensor networks. The sink proactively, dynamically and randomly builds a cluster grid structure in GROUP. Only small part of all sensor nodes will participate in election of cluster heads. GROUP can distribute the energy load among the sensors in the network,...
