This paper introduces a smart data packet routing protocol (SMART) based on swarm technology for mobile ad hoc networks. The main challenge facing a routing protocol is to cope with the dynamic environment of mobile ad hoc networks. The problem of finding best route between communication end points in such networks is an NP problem. Swarm algorithm is one of the methods used solve such a problem....
The integration of mobile wireless devices into grids has recently drawn the attention of research community as this integration has resulted in new challenges. Mobile grid enables the mobility of a requesting user to share unused available resources on a network required in different applications in science, health and education. These handheld devices are not capable to cope with the existing demands...
In Mobile Ad Hoc Network (MANET) many routing protocols exist, which are capable of routing data packets from source to destination. Each protocol is designed to fulfill its requirement; the constant network context (i.e. number of nodes, mobility, etc); but network context could be changed during the running time which affects the protocol performance and reduces its efficiency. In this paper, a...
In wireless communication, ad hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. Routing is a fundamental issue for mobile ad hoc network...
There are many routing protocols proposed for Mobile Ad hoc Networks (MANET). However most of these protocols are analysed by two standard techniques: simulation and security analysis. There has been a lack of work on the analysis and performance of secure routing protocols in real network test-bed. In this paper, a quantitative set of results for the performance comparison between Adaptive On-demand...
In any mobile ad hoc network, a single routing system is in use during communication time without considering the MANET context, in spite the fact that MANET context affects the routing protocol performance. Changes in the MANET context lead to changes in the routing protocol behaviour for better or worse performance. This paper introduces a novel intelligent mobile ad hoc network routing system which...
Routing protocols face many challenges in Mobile Ad Hoc Networks (MANETs) due to the dynamic nature of wireless medium and unpredictable topological changes. This paper proposes On-Demand Link-Weight (ODLW) routing protocol. ODLW selects an optimum route on the basis of link reliability taking in consideration the link bandwidth, delay and node lifetime. The approach is based on Cross- Layer design...
There are many routing protocols proposed for Mobile Ad hoc Networks (MANET) [1]. However most of these protocols are analysed by two standard techniques: simulation and security analysis. There has been a lack of work on the analysis and performance of secure routing protocols in real network test- bed. In this paper, a quantitative set of results for the performance comparison between Adaptive On-demand...
Zone routing protocol (ZRP) is a hybrid MANET protocol. ZRP combines between the proactive routing approach and the reactive approach. The network in ZRP is divided into several zones, where the proactive is applied within each zone. Outside the routing zone, the reactive approach is used. In this paper, a development to ZRP protocol based centralised intra-zone routing is proposed. The proposed concept...
This paper investigates and undertakes simulation-based comparison of on-demand routing protocols in multi ad hoc networks. First, it investigates the factors affecting the performance criteria and working architecture of ad hoc on-demand distance vector (AODV) and optimized link state routing protocol (OLSR). Second, it considers proposing a scenario of multi ad hoc network domains and their inter-communication...
Usually, routing protocols which are based on link-state information such as (OSPF, OLSR, and FSR) compute the shortest routes to each reachable destination using a path-selection algorithm like Dijkstra's algorithm or the Bellman-Ford algorithm. However, in an on-demand link-state routing protocol, there is no need to know the path to every other node. Accordingly, when a node chooses a next hop...
