Ad-hoc networks have become a hot topic in the research world. Routing in ad-hoc networks has faced so many problems due to the peculiar nature of ad hoc environments. In this paper a new routing protocol based on source routing and zone based routing is proposed. Proactive source routing protocol (PSR) is a method to reduce overhead in ad hoc networks by making use of BFSTs (Breadth First Span...

In ad hoc networks, designing a secure routing protocol is critical. The FLSL (FuzzyLogicBased Security-Level Routing Protocol) routing protocol is proposed in this paper. The basic idea of FLSL is to utilize the “local multicast” mechanism and the Security-Level to select the highest Security-Level route. The proposed algorithm of Security-Level is an adaptive fuzzy logic based algorithm that ...

Routing protocol is taking a vital role in the modern communication networks. A routing protocol is a protocol which is responsible to determine how routers communicate with each other and forward the packets through the optimal path to travel from a source node to a destination node. Among the routing protocols, Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (O...

In this paper, we propose a routing protocol for disconnected ad hoc networks where most nodes tend to move about in groups. To the best of our knowledge, no routing protocol for disconnected ad hoc networks has been designed earlier keeping in mind possible group patterns formed by the movement of nodes. Our protocol works by identifying groups using an efficient distributed group membership p...

Internet Engineering Task Force (IETF) working group has standardized the transmission of internet protocol version 6 (IPv6) packets over IEEE 802.15.4 low power wireless personal area network (LoWPAN) as 6LoWPAN protocol. It provides the wireless sensor network (WSN) node with IP communication capabilities by putting an adaptation layer above the 802.15.4 link layer. Different mechanisms perfo...

Efficient routing protocols can provide significant benefits to mobile ad hoc networks in terms of both performance and reliability. Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which need a robust dynamic routing protocol. Many routing protocols for such networks have been proposed so far. Amongst the most popular ones are Dynamic Source Routing (DSR), Ad-h...

Routing protocols are key elements of modern communication networks. Currently deployed dynamic routing protocols that are used to propagate network topology information to the neighboring routers are Routing Information Protocol (RIP), Enhanced Interior Gateway Routing Protocol (EIGRP), and the Open Shortest Path First (OSPF) protocol. The choice of the right routing protocol depends on a numb...

Adhoc networks are characterized by connectivity through a collection of wireless nodes and fast changing network topology. Wireless nodes are free to move independent of each other which makes routing much difficult. This calls for the need of an efficient dynamic routing protocol. Mesh-based multicast routing technique establishes communications between mobile nodes of wireless adhoc networks...

Mobility is one of the important issues in Mobile Ad hoc Networks (MANET). By definition, MANET nodes are free to move around and this may cause difficulty routing. routing protocols must consider factor when making decision. Zone Routing Protocol (ZRP) a hybrid protocol, which utilizes proactive reactive advantages. ZRP proactively maintains information within zone, while reactively discoverin...
