Routing delivery is one of the key techniques in mobile ad hoc network, which involves many aspects such as topology update, routing exchange and so on. In this paper, we firstly apply routing tree to describe the complete topology of ad hoc network, and then store the information of routing tree into every node's routing table. Sparse routing tree, as a pruned tree, is used to exchange topology information,...
In order to achieve the best performance of a Wireless Sensor Network (WSN), it is a must to provide a challengeable routing algorithm , which consumes less power and allows more data collection. In this paper we have considered a WSN with mobile sinks and it is considered that the router follows the basic location update algorithm with traffic awareness. We show the performances of a router under...
A managed wireless mesh for infrastructure-level, stable regional mesh network has been studied. NerveNet, which we have been proposing, is a concept of future regional platform network that covers local regions and provides various context-aware services with the shared use of sensors and actuators. The managed wireless mesh developed for materializing NerveNet features auto-configuration of multiple,...
Wireless sensor networks may be utilized for various application areas such as health, military, home, and so on. In the wireless sensor networks, data transmission typically relies on multi-hop communication with high packet loss rates on wireless links so that reliable end-to-end data transmission is desirable. Recently, in order to achieve desired Communication Reliability (CR) levels of the various...
Indoor Wireless sensor networks require a highly dynamic, adaptive routing scheme to deal with the high rate of topology changes due to fading of indoor wireless channels. Besides that, energy consumption rate needs to be consistently distributed among sensor nodes and efficient utilization of battery power is essential. If only the link reliability metric is considered in the routing scheme, it may...
Since the pioneering research work of Ahlswede et al. in 2000, Network Coding (NC) has rapidly emerged as a major research area in electrical engineering and computer science due to its wide applicability to communication through real networks. The many contributions available in the literature to date, ranging from pure theoretical studies on fundamental limits to practical experimentations in real-world...
System capacity is an important factor that affects the performance of WiMAX system where the amount of data that can be delivered to the end user is determined based on the system capacity and users QoS requirements. This scenario is even more complex when multi-hop relays are introduced into the network whereas the user access capacity decreases with the increase of hop number. In order to maintain...
Wireless mesh network is a new type of network paradigm in which each node communicates to others to enhance network reliability and performance. Routing in wireless mesh network is a challenging task. Despite from the traditional routing, field based routing uses a little information to route the packets. Due to this characteristic, field based routing algorithms are inexpensive and robust, but such...
This paper considers the problem of routing packets across a multi-hop wireless network while ensuring throughput optimality. One of the main challenges in the design of throughput optimal routing policies is identifying appropriate and universal Lyapunov functions with negative expected drift. The few well-known throughput optimal routing policies in the literature are constructed using simple quadratic...
Sensor network is receiving considerable attention as one of the key technologies to keep track of the parameters in the industrial field. Wireless sensor networks (WSN) integrate sensor technology, embedded technology, distributed information processing and network communication. The nodes of WSN serve the functions of perceiving and routing. Power consumption is the key factor affecting the longevity...
Energy-saving is one of the inevitable problems of the routing design in wireless sensor networks. The article obtains network routings by genetic algorithm, and the genetic algorithm has been improved by using data fusion and the model of wireless energy transmission. The simulation results show that the improved algorithm has made great progress in balancing the consumption of energy so as to prolong...
