This paper proposes a simple and effective algorithm to improve the quality of service on the Internet by providing alternate path between source and destination nodes when the delay or packet loss rate on the primary path becomes unacceptable. We combine Source Routing with an Intermediate Node forwarding mechanism to yield a multipath routing mechanism called SIR (Source Intermediate Routing). It...
The ZODIAC project has been exploring a security first approach to networking based on a new idea, the dynamic community of interest, based on groups of users with a demonstrable need to know. ZODIAC uses the most challenging network setting (the mobile ad hoc network) as a target, since each node must incorporate functions of both hosts and routers. The realization of the DCoI is a work in progress,...
Position-based routing protocols in ad hoc networks combine a forwarding strategy with a recovery algorithm. The former fails when there are void regions or physical obstacles that prevent transmission. Then, the recovery algorithm is used to detour the obstacles. To explore the obstacles and find a path around them, the earlier recovery approaches construct a planar graph to avoid routing loops....
