In a Wireless sensor network (WSN) with multi-hop communications, nodes close to a sink drain more battery energy than others in relaying packets, which causes lifetime of the WSN to be shortened. To solve the uneve...

Overlay multicast trees should be built according to three constraints: cost, load balancing and stress. This paper formalizes a function to evaluate the performance of multicast trees in a certain mesh on the three ...
Research is carried on a novel switching fabrie-XD (cross and direct) network, which is the core of the terabit router. XD networks have many advantages such as simple rectangular structure, scalability and so on. A...
The Dynamic source routing protocol(DSR) is an on-demand routing protocol, designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. In this paper, some mechanisms such as the route's lifeti...
