Most existing on-demand mobile ad hoc network routing protocols continue using a route until a link breaks. During the route reconstruction, packets can be dropped, which will cause significant throughput degradation. In this paper, we add a link breakage prediction algorithm to the Dynamic Source Routing (DSR) protocol. The mobile node uses signal power strength from the received packets to pr...

In this paper, we have analyzed the performance of multipath routing protocol with various mobility models for Mobile Ad Hoc Networks. The basic purpose of any multipath routing protocol is to overcome various problems occurs while data delivery through a single path routing protocol. For high acceptability of routing protocol, analysis of routing protocol in ad hoc network only with random way...

A MANET 1 is a set of mobile nodes that are free to move dynamically and unpredictable in environment, but this dynamic nature of the network topology cause for many challenges in MANET. Multicasting is one of methods that because of grouporiented computing are mostly used in MANET routing. Protocols have designed for multicasting in MANETs that ODMRP is one of them. ODMRP is on-demand and mesh...

In Mobile Ad Hoc Network (MANET), the collection of mobile nodes gets communicated without the need of any customary infrastructure. In MANET, repeated topology changes and intermittent link breakage causes the failure of existing path. This leads to rediscovery of new route by broadcasting RREQ packet. The number of RREQ packet in the network gets added due to the increased amount of link fail...

Compared with Geostationary Orbit (GEO) satellite systems and Medium Earth Orbit (MEO) satellite systems, Low Earth Orbit (LEO) satellite systems provide lower propagation delay as well as higher throughput. Because of these reasons, LEO satellite systems can play a pivotal role in providing services to areas where there is no substantial terrestrial infrastructure. In this paper, a novel kind ...

We present BLITZ, a novel link quality estimator that relies on physicallayer synchronization errors to estimate the expected packet delivery ratio of wireless links. In contrast to all existing link quality estimators which estimate the packet delivery based on statistics from packets that are successfully decoded, our technique works even when packets at the receiver are not correctly receive...

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes in which different routing protocols are used to form the communication network. So, far there are numerous routing protocols are discovered in which AODV performs superior than all. Ad-hoc network suffer from the bunch of issues in which congestion and security are the major issues of concern which leads to severe degrada...

In this paper, we propose an autonomous transmission timing control scheme for collision avoidance in ad hoc multicasting. In ad hoc multicasting, packet collisions due to hidden node problems at upstream nodes cause packet losses at all downstream nodes. Therefore, collision avoidance mechanisms are important to improve packet delivery ratio at destination nodes. In this paper, we extend an On...

Mobile nodes of various routing protocols in Mobile Ad hoc Networks follow different strategies in transmission and receiving of data. Security, packet delivery and routing overhead are important concerns for any protocol during designing them. The presence and absence of malicious nodes in the network affect a lot on the performance of the protocol. This research is mainly focused on the study...
