The Hierarchical Optimized Link State Routing (HOLSR) protocol was designed to improve scalability of heterogeneous Mobile Ad-Hoc Networks (MANETs). HOLSR is derived from the OLSR protocol and implements Multipoint Relay (MPR) nodes as a flooding mechanism for distributing control information. Unlike OLSR, nodes are organized in clusters and implement Hierarchical Topology Control (HTC) messages for...
A typical broadcasting protocol for wireless network usually involves fixed transmission power that covers, for example an area within 250 meters (m). However, it is often unnecessary to broadcast using fixed power because a node that needs to be covered may just be 100m away. By reducing the transmission power enough to cover this node, energy expenditure would be reduced, thus, prolonging the lifetime...
In this paper, the problem of localized routing in mobile ad hoc networks is considered. In localized routing algorithms, messages are forwarded by each node based on its own geographic location, the location of its neighbors and the destination. In this work, a set of new geographic or position-based routing algorithms called the Randomized Greedy-AB-Greedy (RGABG) for routing in mobile ad hoc networks...
