A mobile ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure. A number of routing protocols like Destination Sequenced Distance Vector Routing (DSDV), Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV) have been implemented. This paper presents the comparative perform...

Integrated optical interconnect is believed to be one of the main technologies to replace electrical wires. Optical Network-on-Chip (ONoC) has attracted more attentions nowadays. Benes topology is a good choice for ONoC for its rearrangeable non-blocking character, multistage feature and easy scalability. Routing algorithm plays an important role in determining the performance of ONoC. But trad...

The routing problem for shared path protection in multi-domain optical mesh networks is difficult due to the lack of complete and global knowledge on the network topology and bandwidth allocation. To overcome this difficulty, we propose an aggregated network modeling by overestimation with a two-step routing strategy. In the first step, a rough routing solution is sketched in a compact network ...

This thesis proposes a network coding based and easily-realizable composite network topologic model. It is composed of disjoint multi-path routing (DMR) and braided multi-path routing (BMR) in wireless sensor network, and network coding technology is also employed in our multi-path routing. With the use of the Node Coding technology and the multi-path technology, NC-RMR (Network Coding based Re...

Ad-hoc networking is a concept in computer communications, which means that users wanting to communicate with each other form a temporary network, without any form of centralized administration. Each node participating in the network acts both as a host and as a router. The study of distributed network and mobile ad hoc network (MANET) are currently two hotspots in distributed computing and mob...

This article puts forward the routing algorithm of wireless sensor network based on ant colony optimization. The algorithm uses the characteristics of ant colony algorithm that is easy to realize local work, integrates link quality into the pheromone formation and supports multiple routes. When choosing routing, the probability is calculated that the node is selected as the next hop according t...

Ad hoc wireless network is experiencing challenges due to various security issues and resource constraints in nature high mobility. There is always the challenge to create a reliable and optimized network for efficient routing. Ensuring a dynamic way that path which is known in communications is always a challenge in the mobile ad hoc network. Most of the existing secure routing protocols will ...

This paper studies the impact of resource reservation on the multi–path Quality–of–Service (QoS) routing schemes that use global network state to make routing decisions. Incorporating resource reservation into multi–path QoS routing algorithms greatly changes the communication characteristics in a network system and affects the performance of the routing algorithms. In this paper, we develop a ...

wireless sensor networks are the new generation of networks that typically are formed great numbers of nodes and the communications of these nodes are done as wireless. the main goal of these networks is collecting data from neighboring environment of network sensors. since the sensor nodes are battery operated and there is no possibility of charging or replacing the batteries, the lifetime of ...
