Numerous routing protocols have recently been developed for ad hoc mobile networks. Routing protocols to date can be categorized as either ‘table-driven’ or ‘on-demand’. Many of the proposed routing protocols take the on-demand approach because this does not require keeping lots of routing information. However, these kinds of protocols are not able to react fast enough to maintain routing. In t...

This paper discusses the analysis and evaluation of routing protocols in wireless sensor network, routing protocol for wireless sensor network based on the topology structure can be divided into planar and hierarchical. WSN communication protocol stack can be divided into physical layer, data link layer, network layer, transports layer and application layer. Finally this paper introduces the ty...

Energy consumption of the nodes is an important issue while designing multicast routing algorithms for MANETs’ and therefore, an efficient routing protocol needs to be energy conserving so that battery life of each individual node as well as lifetime of the network can be prolonged. This paper proposes a power efficient multicast routing protocol for mobile ad hoc networks called “Power Aware M...

In this work we propose an UML modeling of the “Greedy Perimeter Stateless Routing” (GPSR) protocol that integrate this geographic routing protocol, into "JavaNetwork Simulator" to simulate and study this protocol in a first time and offer some improvement in these features. Java Network Simulator (JNS) is a project of "translation" of Network Simulator (NS) in Java initiated by "the UCL Depart...

This chapter provides history of routing to cognitive routing . Firstly i t reviews hardwired routing a kind of switching to dynamic routing for telecommunication network starting with dynamic alternate routing (DAR) to ATM (Asynchronous Transfer Mode) routing. Secondly it presents routing in data network or packet switching. Thirdly it reviews routing for wireless multi hop network with specia...

In MANETs, there are many routing protocols like table-driven and on-demand routing protocols. Among these protocols, on-demand routing protocols are very sensitive in achieving the major challenges of MANET such as routing, security, bandwidth, quality of service and reliability and so on. The most popular on-demand routing protocols are Ad-hoc On-demand Distance Vector (AODV), Dynamic Source ...

This paper presents a novel routing protocol for Disruption Tolerant Networks (DTNs) called Efficient DTN Routing Protocol (EDRP). EDRP smartly integrates the forwarding and buffer management policies into an adaptive protocol that includes a local network parameters estimation mechanism. It dynamically adjusts the delivery probability for messages according to a new metric. Meanwhile, EDRP arr...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...

Ad hoc networks are gaining increasing popularity in recent years because of their ease of deployment. No wired base station or infrastructure is supported, and each host communicates one another via packet radios. In ad hoc networks, routing protocols are challenged with establishing and maintaining multihop routes in the face of mobility, bandwidth limitation and power constraints. In this pa...

Routing is fundamental to the workings of the internet, yet the basic routing protocol, Border Gateway Protocol (BGP), is known to be insecure. This paper uses institutional economics to examine internet routing registries, which are used by network operators to mitigate the security flaws in BGP. Secure routing of internet traffic is characterised as a problem in the distributed governance of ...
