Limited by the terrain, lots of Wireless sensor network (WSN) applications have to be deployed in a narrow strip area. Due to the narrow and strip network structure, traditional WSN routing algorithms such as LEACH and PEGASIS can not be applied in such applications directly, it’s very necessary to develop a new routing protocol suit for the strip WSN. In order to improving communication efficiency...
In this paper we are proposing an efficient secure solution to the data centric routing protocol One Phase Pull diffusion which permit multi-hop routing of sensed data. SecOPP provides both Group and Pairwise key distribution with the possibility of rekeying as well as security services: integrity, authentication and confidentiality of exchanged messages. All these are obtained without using a key...
Delay Tolerant Network (DTN) is evolved from Mobile Adhoc Network, MaNet. It is sparse and intermittently connected mobile adhoc network where reliable communication and end-to-end connectivity is not available for message transmission. The end to end connectivity is not ensured in Delay Tolerant Network. Only high latency applications are used in DTN. Latency may be in hours or days. The store and...
Delay Tolerant networks (DTNs) are one type of wireless networks where the number of nodes per unit area is small and hence the connectivity between the nodes is intermittent. In this case, the performance in terms of transport of information from source to destination relies on the mobility of the nodes which would cause their encounters and hence the relay of information from one node to another...
This paper proposes a new position-based Routing protocol for Mobile Ad hoc networks, referred to as FORTEL. According to FORTEL, each node in the network maintains a location table that stores the location of all the other nodes. To discover a route to the destination, the source node relies on the location table to construct the destination's connectivity tree, which includes all the destination's...
In recent years, ad-hoc network technology consisting of not access points and base stations but of wireless nodes has gained attention because the disaster scene requires quickly construction of the network. Usually the aim of routing protocol in ad-hoc network is to provide the stable network service. In order to maintain the network, node must communicate with each other in exchanging their routing...
The stringent requirement for the high efficiency of routing protocol on Internet will be satisfied by exploiting the threaded border gateway protocol (TBGP) on multi-cores. Since the TBGP performance is restricted by a mass of contentions when racing to access the routing table, a highly-efficient parallel access approach is originally proposed to achieve the ultra-high route processing speed. In...
Wireless mesh networks (WMNs) have attracted increasing attention and deployment as a high-performance and low cost solution to last-mile broadband Internet access. Wireless mesh networks have emerged as a potential technology for next-generation wireless networking. WMNs have been widely accepted in the traditional application sectors of ad hoc networks because of their advantages over other wireless...
Mobile Adhoc Networks (MANETs) is a wireless network which does not require any infrastructure and base station for communication. A routing protocol with less energy consumption is one of the main requirements of MANET because of limited bandwidth and battery power of each node. In this paper we have proposed a new algorithm called ECG_AODV (Energy Constraint Gossip based) routing protocol and analyzes...
Wireless ad hoc networks are a collection of mobile nodes spreading over a defined geographical area, enabling realtime collaborative applications such as push-to-talk and VoIP. Unfortunately, wireless ad hoc networks suffer from limited bandwidth and QoS constraints. A proposed eXplicit MultiCAST (XCAST) based routing protocol (P-XCAST) is presented in this paper to support team-based communications...
Wireless ad hoc networks using omni-directional antennas do not scale well due to interference between nearby nodes. Maintaining the QoS of the communications in this type of network is a difficult task. Using multiple narrow beam directional antennas alleviates this problem at the expense of connectivity. Multi-beam smart antennas allow the network topology to be adjusted dynamically by adjusting...
In order to establish a trusted and secure wireless mesh network, routing protocols should not only ensure the integrity, confidentiality and authentication, but also take into consideration the fact that the application of routing strategies should not impact the performance of routing protocols to a severe extent. This paper adopts Node's Trust as a routing parameter, and some improvements are made...
Wireless ad hoc networks are a type of wireless network that can be easily created without the need of network infrastructure or central administration. Unfortunately, wireless ad hoc networks suffer from some limitations related to the bandwidth leakage. So a proper data flow mechanism should be used to save the bandwidth consumption. So we proposed an XCAST based routing protocol (P-XCAST) to be...
Routing is a challenging task in mobile adhoc network due to nodal mobility, unstable links and limited resources. Swarm intelligence, as demonstrated by biological swarm, such as ant colony has found to be a attractive technique for routing in MANET. However existing swarm intelligence based routing protocols find an optimal path by considering only one or two route selection metrics, such as hop...
IEEE 802.11 proposed a number of standards and each one had a specific goal. They can be configured in infrastructure mode or ad hoc mode. In the study of infrastructure mode, the focus was on 802.11 b/g co-existence along with other single mode operations to analyze the throughput and traffic drop through simulation. In the study of ad hoc mode, the focus was to analyze the behavior of ad hoc networks...
Autonomous Systems such as Internet Service Provider (ISP), Enterprise Networks and Academic Networks provide Internet services like internet transit, domain name registration and hosting, dial-up access, leasedline access and co-location. Simulation provides an insight into the behavior of these AS. The internal details like designing, configuring and maintaining networks through protocols that include...

In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage, thus opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where the participating nodes do not rely on any existing network infrastructure. By definition, the nature of ad hoc networks is dynamically changing and they have a fully decentralized...
Border Gateway Protocol version 4 (BGP-4) is the routing protocol for inter-domain routing in the Internet. Although BGP-4 is a scalable distributed routing protocol, BGP propagates only the selected best path for a destination to other autonomous systems. This property and long convergence delay in BGP have been known to cause serious inefficiency in network resource utilization and vulnerability...
Wireless sensor networks (WSNs) consists of unattended sensors with limited storage, energy (battery power) and computation and communication capabilities.
