A Review of Current Routing Proto cols for Ad-Ho c Mobile Wireless Networks Elizab eth M. Royer C-K Toh Dept. of Electrical Computer Engineering Dept. of Electrical Computer Engineering University of California, Santa Barbara Georgia Institute of Technology, Atlanta eroyer@ cktoh@ Abstract An ad-ho c mobile network is a collection of mobile no des that are dynamically and arbitrarily lo cated in such a manner that the interconnections b etween no des are capable of changing on a continual basis. In order to facilitate communication within the network, a routing proto col is used to discover routes b etween no des. The primary goal of such an ad-ho c network routing proto col is correct and ecient route establishment b etween a pair of no des so that messages may b e delivered in a timely manner. Route construction should b e done with a minimum of overhead and bandwidth consumption. This pap er examines routing proto cols for ad-ho c networks and evaluates these proto cols based on a given set of parameters. The pap er provides an overview of eight dierent proto cols by presenting their characteristics and functionality, and then provides a comparison and discussion of their resp ective merits and drawbacks. 1 Intro duction Since their emergence in the 1970s, wireless networks have b ecome increasingly p opular in the com- puting industry. This is particularly true within the past decade which has seen wireless networks b eing adapted to enable mobility. There are currently two variations of mobile wireless networks. The rst is known as infrastructured
