Two fundamental problems in any cellular systems are limited capacity and the presence of unbalanced traffic. In this paper, we propose a novel grouping infrastructure for next generation cellular networks, whose objective is to increase the system throughput and further improve the system balance. In the cellular system, we consider all the available users are divided into two groups. One is the...
Video capture and transmission play an important role in mobile ad hoc network (MANET) applications, and the routing protocol has vital impacts on the design of network performance. In this paper we designed and achieved an embedded video capture and transmission system which used an improved routing protocol AODV-SBR (AODV-simple backup route). The results indicated the video transmission system...
Ad hoc networks in which nodes communicate via multi-hop, without wired infrastructure have been considered as excellent candidates for tactical military communications. In this paper, we present a routing scheme suitable for tactical networks, which combines zone routing protocol and backbone networks. With the introduction of backbone nodes, message to nodes outside of routing zone is relayed though...
Broadcasting is a common algorithm of on-demand ad hoc routing protocols for its simplicity and reliable accessibility. However, blind broadcasting often incurs collision, contention, and redundancy, which are called broadcast storms. As a countermeasure, we propose a conditioned broadcasting approach, by allowing each intermediate node decides whether to rebroadcast or not based on neighbourhood...
