In Mobile Ad hoc Network (MANET) all the nodes are freely moves in the absence of without ant centralized coordination system. Due to that the attackers or malicious nodes are easily affected that kind of network and responsible for the routing misbehavior. The routing is network is mandatory to deliver data in between source and destination. In this research we work on security field in MANET ...

Efficient operation of multipath routing is considered as one of the important aspects in MPLS traffic engineering. Multipath routing has an advantage over the traffic routing based on single shortest path because single path routing may lead to unbalanced traffic situations and degraded QoS (Quality of Service). The adequate strategy for the order of repairing failed links can greatly influenc...

Mobile ad hoc networks are typically characterized by high mobility and frequent link failures that result in low throughput and high end-to-end delay. The increasing use of MANETs for transferring multimedia applications such as voice, video and data, leads to the need to provide QoS support. We introduce a routing algorithm, Ad hoc on-demand multipath routing, which provides quality of servic...

Nodes in a sensor network, operating on power limited batteries, must save power to minimize the need for battery replacement. We note that the range of transmission has a significant effect on the power consumption of both the transmitting node and listeners. This paper first presents a Geographical Power Efficient Routing (GPER) protocol for sensor networks. Each sensor node makes local decis...

Vehicular Ad hoc Networks (VANETs) are a specific class of Mobile Ad hoc Networks (MANETs). Since vehicles tend to move in a high speed, the network topology is rapidly changed. Thus vehicle’s connectivity problem is one of the interesting issues in VANETs. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extended version of ad hoc on-demand distance vector (AODV). AOMDV is designed to ...

Existing multipath routing protocols in MANETs ignore the topology-exposure problem. This paper analyzes the threats of topology-exposure and propose a TOpology-HIding multipath Protocol (TOHIP). TOHIP does not allow packets to carry routing information, so the malicious nodes cannot deduce network topology and launch various attacks based on that. The protocol can also establish multiple node-...

In this In MANET (Mobile Ad hoc Network) nodes are not fixed on one position that’s why proper communication is very critical issue. The nodes in MANET depend on battery for communication. Therefore energy efficiency is an important design deliberation to extend the lifetime of networks. The cluster based approach provides the efficient communication in the form of group. The nodes in Mobile ad...

This report details an investigation of a scheme for multipath routing. We summarize a scheme for multipath routing with flat distribution on a cubic grid. We critique this method and define an objective against which this can be measured. The applicability of these techniques to multipath routing in a more general network in investigated and a new scheme is proposed. Also many open questions f...

With respect to the inherent advantages of multipath routing, nowadays multipath routing is known as an efficient mechanism to provide even network resource utilization and efficient data transmission in different networks. In this context, several multipath routing protocols have been developed over the past years. However, due to the time-varying characteristics of low-power wireless communic...

Shin, Dong-won. Ph.D., Purdue University, August, 2003. Multicriteria routing for guaranteed performance communications. Major Professors: E. K. P. Chong and H. J. Siegel. In this thesis, we investigate two routing problems. The first, which is known as the multiconstraint QoS (quality of service) routing problem, is to find a single path that satisfies multiple QoS constraints. For this proble...
