The performance of routing protocols in mobile ad hoc network (MANET) always attracts many attentions. As many previous works have shown, routing performance is greatly dependent to the availability and stability of wireless links. Although there are some studies reported to evaluate the performance of routing protocols in MANET, little work is done for the system overall performance, which is generally...
This paper aims at adding quality of services (QoS) extensions to the associativity based routing (ABR). The performance analysis of the ABR with QOS support is the same as ABR except for more computation on the intermediate nodes to comply with the QOS requirements and the size of the control messages will be varying. But the total number of operations performed and total number of messages exchange...
In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage, thus opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where the participating nodes do not rely on any existing network infrastructure. By definition, the nature of ad hoc networks is dynamically changing and they have a fully decentralized...
Traditional gossip-based protocols rely on underlying routing protocols to disseminate messages. In mobile ad hoc networks, frequent topology changes may incur many route errors, which increase the overhead of maintaining routing information. They also need to maintain a partial or global view of the network, which further increases the overhead. This paper presents a broadcast gossip protocol based...
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...
In this paper an efficient on demand QoS based routing protocol is developed which considers end to end application requirement and energy efficiency together with the route discovery mechanism of DSR to set up QoS route. The proposed QoS aware protocol works as per the user request for a route. If a request comes for QoS route, based on some application requirement (available bandwidth, transmission...
A mobile ad hoc network (MANET) 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. The primary goal of such an ad-hoc network routing protocol is correct...
This paper shows a novel technique for routing protocol in ad hoc network, namely simplified receiver assisted routing enhancement (RARE). Simplified mathematical model has been explained to analyze the performance of RARE algorithm. In this algorithm, we use the principle of the biologically inspired ant routing technique to evolutionally maintain the routing information. The similarities and differences...
Mobile ad hoc network (MANET) faces serious security threat due to lack of consideration of security in design and inherent weaknesses. Anomaly detection techniques as well as preventive measures are in urgent need to protect ad hoc network. We propose an innovative anomaly detection technique based on temporal analysis of routing activities. Our approach uses data mining techniques to discover the...
To meet the needs of QoS requirement of multimedia traffic in wireless networks, IEEE 802.11e protocol has been proposed as an upcoming standard. The medium access control (MAC) layer of 802.11e has provided QoS support through priority scheduling for different types of traffic. However, the 802.11e QoS mechanism has an impact on the higher layers i.e. network layer and create new issues that need...
