Multipath routing protocols for Mobile Ad hoc NETwork (MANET) addresses the problem of load balancing, scalability, security and life time of networks. In this paper, we propose a new multipath protocol, Stability and Energy Aware Multipath Ad hoc On-demand Distance Vector (SEAM-AODV) protocol which is an enhancement of Ad hoc On-demand Distance Vector (AODV) protocol. It designs a bi-objective...

A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and several of them have be...

Decreasing the route rediscovery time process in reactive routing protocols is challenging in mobile ad hoc networks. Links between nodes are continuously established and broken because of the characteristics of the network. Finding multiple routes to increase the reliability is also important but requires a fast update, especially in high traffic load and high mobility where paths can be broke...

Cognitive radio networks (CRNs) have emerged as a paradigm addressing the problem of limited spectrum availability and the spectrum underutilization in wireless networks by opportunistically exploiting portions of the unused spectrum by licensed primary users (PUs). Routing in CRNs is a challenging problem due to the PU activities and mobility that are beyond the control of CRNs. On the other h...

In this paper we present a routing scheme for on-demand construction of multiple non-interfering paths in wireless sensor networks. One usage of this multipath scheme is to provide a source the ability to increase the likelihood that its data reaches the sink by sending a copy of a packet on more than one path. The routing scheme is based on the assumption that the sensor nodes are aware of the...

-Security in wireless network is of a great concern in the present wireless environment. Security is becoming a much essential part in wireless communication as intruders are very much keen in attacking the transmitted route or any node to steal the da ta packets It is indispensable to provide security to the network from the intruders and their security attacks. In order to provide a secured e...

Energy consumption is a significant issue in ad hoc networks since mobile nodes are battery powered. In order to prolong the lifetime of ad hoc networks, it is the most critical issue to minimize the energy consumption of nodes. In this paper, we propose an energy efficient multipath routing protocol for choosing energy efficient path. This system also considers transmission power of nodes and ...

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 ...

Due to mobility in Ad-Hoc network the topology of the network may change randomly, rapidly and unexpectedly, because of these aspects, the routes in the network often disappear and new to arise. To avoid frequent route discovery and route failure EAOMDV was proposed based on existing routing protocol AOMDV. The EAOMDV (Enhanced Ad-Hoc on Demand Multipath Distance Vector) Routing protocol was pr...
