A new energy-efficient wireless sensor network routing algorithm is proposed. The algorithm obtains optimization routing paths using global information of wireless sensor network. And the optimizing process can be reproduced in distribution by constructing a neural network for each node. Simulation results show the algorithm can accomplish routing process correctly and rapidly, and increase network...
To enable services such as streaming multimedia and voice in multi-hop wireless networks it is necessary to develop algorithms that guarantee Quality of Service (QoS). In this paper, we consider the problem of optimal routing and admission control for flows which require a pre-specified bandwidth from the network. We develop an admission control and routing algorithm whose performance is close to...
The proposed algorithm selects the path under reliability constraint with minimum total power consumption and maximum nodes?? residual battery (RCEB) to balance energy and maximize the network lifetime. An evaluation function of objective optimization degree is formatted. A new heuristic algorithm with pseudo polynomial-time complexity is proposed to simplify the solution of this nonlinear programming...

Theoretical analyses and experimental results show that, compared with conventional works, the new algorithm has better anti-monitoring performance which...
With the rapid growth of population and technology, the electric power consumption and number of utility consumers had increased quickly. In order to serve larger utility- consumers, the automatic meter reading (AMR) systems are widely used. In the wireless data acquisition systems such as ARM and temperature-humidity, the process of data transmission through wireless means, the routing algorithm...
In this paper, we propose a reliable and energy-efficient routing algorithm for underwater wireless sensor networks (UWSNs). We first use a sphere energy depletion model to analyze the energy consumption of nodes in UWSNs. We then extend the model by considering the node mobility in UWSNs. Our analysis is in accordance with the common view that although water flows might cause the underwater environment...
This work investigates the utilization of a new pheromone distribution model for ANCOR. ANCOR is a novel routing algorithm for sensor networks. The main idea behind the algorithm is imitating the real acts of ants for finding new food resources and bringing them to their nests. A new pheromone distribution model for ANCOR, i.e. optimal pheromone distribution model will be presented, and its performance...
Energy balance is an important performance index in the design of routing algorithm for wireless sensor networks. A swarm intelligence optimization based routing algorithm for wireless sensor networks is proposed, whose kernel idea is taking less hop numbers into consideration and choosing the nodes with less pheromone as next hop to avoid some nodespsila prematurely exhausting their energy because...
