This paper presents a Dynamic Source Routing Protocol using Self Healing and Optimizing Routing Technique based on fuzzy logic concepts. The paths generated by conventional dynamical source routing protocol deviate far from the optimal paths because of the lack of knowledge about the global topology and the mobility of nodes. Routing optimality affects the network performance, especially when t...

Secure data transfer in mobile ad hoc network (MANET) against malicious attacks is of immense importance. In this paper, we propose a new enhanced trust model for securing the MANET using trust-based scheme that uses both blind and referential trust. order to do this, relationship function has be integrated with dynamic source routing (DSR) protocol making more secure. We thoroughly analyze DSR...

This paper describes the concept of routing in wireless sensor networks. Routing algorithm provides reliable path from source to destination. Energy efficiency is main constraint in Wireless Sensor Networks. For improving life time and energy consumption various routing algorithms have been proposed. In this paper describe the hierarchical routing techniques. Hierarchical routing includes tree ...

Wireless mesh networks (WMNs) which mediates the broadband Internet access, have been recently received many attentions by the researchers. In order to increase capacity in these networks, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi-channel WMNs (MRMC WMNs). Therefore, a vital challenge that poses in MRMC WMNs is how to properly assign channels ...

The Mobile Ad hoc Networks playing critical role in network aided communication requirements. The features such as ad hoc and open architecture based connectivity and node mobility are elevating the mobile ad hoc networks as much as feasible to deploy and use. The direct communication between any of two nodes in this network is possible if target node is in the range of source node. If not, the...

We introduce the concept of NIx{Vector routing which gives eecient and consistent routing of packets in Internet routers. A NIx{Vector is a compact representation of a routing path, which is small enough to be included in a packet header. We show how, by including the routing information in the packet header, routing decisions can be made in O(1) time at each router, with no caching or state in...

-Sensor networks consist of large number of nodes with limited energy, computation and transmission power. Each node in the network helps every other node by forwarding their packets to reach the destination .Since these nodes operate in a physically insecure environment; they are vulnerable to different types of attacks such as sinkhole and wormhole. These attacks can inject malicious packets ...

Ad hoc routing protocols that use broadcast for route discovery may be inefficient if the path between any source-destination pair is frequently broken. We propose and evaluate a simple mechanism that allows fast route repair in on demand ad hoc routing protocols. We apply our proposal to the Ad hoc On-demand Distance Vector (AODV) routing protocol. The proposed system is based on the Controlle...
