Rules of Designing Routing Metrics for Greedy,
Face, and Combined Greedy-Face Routing

Yujun Li, Yaling Yang, and Xianliang Lu


Abstract

Different geographic routing protocols have different requirements on routing metric designs to ensure proper operation.
Combining a wrong type of routing metrics with a geographic routing protocol may produce unexpected results, such as geographic
routing loops and unreachable nodes. In this paper, we propose a novel routing algebra system to investigate the compatibilities

Abstract In recent years, there has been a significant amount of work done in developing low-complexity scheduling schemes to achieve high performance in multihop wireless networks. A centralized suboptimal scheduling policy, called Greedy Maximal Scheduling ( GMS) is a good candidate because its empirically observed performance is close to optimal in a variety of network settings. However, its distributed realization requires high complexity, which becomes a major obstacle for practical implementation. In this paper, we develop simple distrib ....etc

A wireless sensor network (WSN) typically operates in an unreliable wireless environment with power restrictions. Many researchers are primarily interested in the energy awareness and communication reliability of WSN to maximize the useful life of the network. However, addressing the conflicting issues of improving energy efficiency and fault tolerance simultaneously is a difficult task. Most of the previous studies have shown that both problems can be addressed through the use of data link or network layer protocols. In this article, we presen ....etc

Abstract Broadcast is an essential and widely used operation in multihop wireless networks. Minimum latency broadcast scheduling (MLBS) aims to find a collision-free scheduling for broadcast with the minimum latency. Previous work on MLBS mostly assumes that nodes are always active, and, thus, is not suitable for duty-cycled scenarios. In this paper, we investigate the MLBS problem in duty-cycled multihop wireless networks (MLBSDC problem). We prove both the one-to-all and the all-to-all MLBSDC problems to be NP-hard. We propose a novel approx ....etc

Abstract :-
Multihop wireless networks rely on node cooperation to provide multicast services. The multihop communication offers
increased coverage for such services but also makes them more vulnerable to insider (or Byzantine) attacks coming fromcompromised nodes that behave arbitrarily to disrupt the network. In this work, we identify vulnerabilities of on-demand multicast
routing protocols for multihop wireless networks and discuss the challenges encountered in designing mechanisms to defend againstthem. We propose BSMR, a novel se ....etc

Abstract A fundamental question in multihop wireless network protocol design is how to partition the network's transport capacity among contending flows. A classically fair allocation leads to poor throughput performance for all flows because connections that traverse a large number of hops (i.e., long connections) consume a disproportionate share of resources. However, na vely biasing against longer connections can lead to poor network utilization, because a significantly high fraction of total connections are long in large networks with s ....etc
