Ad hoc networks are composed of a set of mobile and wireless nodes. They have several characteristics such as being self-organized, dynamically changing topology and multi-hop connectivity. Ad-Hoc On-Demand Distance Vector Routing (AODV) is one of the most widely researched on-demand ad hoc routing protocols. An improvement of the route discovery process in AODV (IMAODV) is proposed to decrease the...
Reactive routing protocol (such as DSR) is preferred in Ad Hoc networks. In DSR protocol, the relay node would search its cache for an alternate route to the destination to salvage packets when link failed and would abandon the packets if not found. This paper introduced a novel routing algorithm based on the downstream nodes' information called DSR-DI. If the alternate route to destination was not...
Most ad hoc routing protocol select route based on shortest path mechanism, which do not take network load into consideration and may lead to congestion in the path selected, the lifetime of network nodes will be reduced. This paper puts forward an adaptive dispersive mobile ad hoc routing protocol(ADMAR) ,which can disperse the network load reasonably, and reduce the possibility of occurrence of...
Broadcasting is a vital communication mechanism in mobile ad hoc networks, as it is the key element for exchanging control packets to support some services such as management and routing protocols. Simple Flooding, which is mostly used as the broadcasting mechanism, is neither resource efficient nor reliable especially in high populated and dense networks. The distance-based (DB) scheme is one of...
In this paper, we purpose a new routing protocol based on applications of hierarchical routing protocols, named as ldquoMulti-Level Cluster-based Hierarchical Protocolrdquo (MLCP) for large-scale mobile ad hoc networks. Our approach organizes nodes into different levels of clusters. MLCP maintains a hierarchical topology, where elected cluster-heads at lower level do not participate to next cluster-head...
This paper introduces the usage and development of mobile ad hoc UAV (unmanned aerial vehicles) network firstly, then, brings forward some problems of ad hoc UAV network presently, and gives some related research topics about mobile ad hoc UAV fleet network, especially routing protocol and date integrity technologies. Finally, give a conclusion about our preliminary studies and this paper.
Mobile ad-hoc networking (MANET) facilitates wireless devices to communicate with each other directly or via multiple hops without utilising existing infrastructure. Due to mobility of the nodes, possible sparse population, limited transmission power, and node failure, ad hoc networks are prone to performance degradation. To address the potential performance degradation non-randomness was introduced...
