Position aided routing protocols can offer a significant performance increase over traditional ad hoc routing protocols. These routing protocols use geographical information to make forwarding decisions, resulting in a significant reduction in the number of routing messages. However, current position aided routing protocols were not designed for use in high-risk environments, as position inform...

This paper evaluate several routing protocols for wireless ad hoc network with packet level simulations in ns-2 environment. The protocol suite includes routing protocols specially designed for wireless ad hoc routing they are more traditional protocols, like link state and distance vector; used for dynamic networks, Performance is evaluated with respect to packets delivery, end-to-end delay an...

Recently, many researchers have focused on the Ad-Hoc networks especially the routing protocols which include reactive and proactive routing protocols. The ultimate goal of routing protocols is forwarding data packet from the source to the destination. Consequently, several proactive routing protocols, such as routing information protocol (RIP), and reactive routing protocols, such as Dynamic S...

heretofore several position-based routing protocols have been developed for mobile ad hoc networks. many of these protocols assume that a location service is available which provides location information on the nodes in the network.our solutions decrease location update without loss of query success rate or throughput and even increase those.simulation results show that our methods are effectiv...

An energy efficient routing protocol is the major attentiveness for researcher in field of Wireless Sensor Networks (WSNs). In this paper, we present some energy efficient hierarchal routing protocols, prosper from conventional Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol. Fundamental objective of our consideration is to analyze, how these extended routing protocols work in...

In this paper, we investigate how service discovery protocols can be improved in Mobile Ad-Hoc Networks by utilizing routing information from the network layer. We consider in this paper proactive routing protocols as the underlying routing protocols and optimize proactive service discovery protocols. We first propose a general framework for the cooperation of service protocols and routing prot...

The wireless sensor network is rapidly growing field as many sensor manufacturers are focusing on technological research and improvements in wireless sensing technology. Recent advances in wireless sensor network have led to many new protocols specifically designed for routing to reduce energy consumption, increase life time of sensor network, reduce overhead and so on. Routing protocols are di...

A mobile ad hoc network (MANET) is a wireless network that uses multi-hop peer-to-peer routing instead of static network infrastructure to provide network connectivity. MANETs have applications in rapidly deployed and dynamic military and civilian systems. The network topology in a MANET usually changes with time. Therefore, there are new challenges for routing protocols in MANETs since traditi...

Multicast 1 is one of the best available service models for scalable, manyto-many delivery of data on the Internet. Multicast achieves scalability by letting sources send a packet only once, regardless of the number of receivers. In network-layer multicast, network elements (routers, switches, and so on) replicate packets at network branching points, delivering copies to all interested receiver...
