Abstract:An ad-hoc network is the cooperative engagement o f a collection of Mobile Hosts without the required intervention of any c e n tralized Access Point. In this paper we present an innovative design for the operation of such ad-hoc networks. The basic idea of the design is to operate each Mobile Host as a specialized router, which periodically advertises its view of the interconnection topology with other Mobile Hosts within the network. This amounts to a new sort of routing protocol. We have i n vestigated modi… Show more

“…If a path is broken between two nodes node n and node u, node n send a notification to the source node, starts re-computation of a route from itself to destination, and drops every subsequent packet that it receives until the re-computation gets completed.

Abstract-An essential matter for ad hoc networks is routing protocol design which is a major technical challenge due to the mobility of the nodes. Routing problem becomes more complex and challengeable, and it probably is the most addressed and studied problem in ad hoc networks. There are several classifications of Routing protocols are used to perform routing the information from source to destination. Classification methods help researchers and designers to understand distinct characteristics of a routing protocol and find its relationship with others. The main aim of this paper is to explore and to compare the concept of all routing protocol based on update mechanism. This classification divided into Table-Driven (Proactive), On-demand (Reactive), Hybrid routing protocols. Also, the comparison is provided based on the routing mechanism and information used to make routing decisions. Also this paper presents an overview of routing issues in different cases as well as a detailed discussion of and their relative performance. To compare and analyze an ad hoc network routing protocols, appropriate classification methods are important.

“…In this case, the protocol is considered proactive, which is also known as table driven. Examples of proactive routing protocols include destination sequenced distance vector (DSDV) [8] and OLSR [9]. On the other hand, if nodes in the network do not always maintain routing information, when a node receives data from the upper layer for a given destination, it must first find out about how to reach the destination.…”
Abstract-MANET is a self organized and self configurable network without existing infrastructure. It consists of several mobile wireless nodes. A routing protocol provides an efficient route between mobile nodes within the network. The discovery and maintenance of route should consume minimum overhead and bandwidth. In this paper, we introduce a novel Proactive Source Routing protocol that has a very small communication overhead. The proposed work is an efficient and improved light-weight proactive source routing protocol for MANETs that utilizes two common searching algorithms, called breadth first search (BFS) and depth first search (DFS) to discover the route. In such method, every node of the wireless network contains a neighbour table. Such table contains each node and its neighbours with distance between them. Therefore, each node has a full topology of the wireless network which is useful to discover the route. Periodic information exchange is used to update such table. We analyze the solution of routing in MANET and evaluate its performance using Network Simulator-2 (NS-2) under different network parameters.
“…Table-driven algorithms, such as e.g. Destination-Sequenced Distance-Vector Routing (DSDV) [36], are purely proactive: all nodes try to maintain routes to all other nodes at all times. This means that they need to keep track of all topology changes, which can become difficult if there are a lot of nodes or if they are very mobile.…”
Abstract. We address failure location and restoration in both optical and wireless ad hoc networks. First, we show how Maximum Likelihood inference can improve failure location algorithms in the presence of false and missing alarms. Next, we present two efficient algorithms for mapping an IP network on an optical network in such a way that it is protected against failures at the optical layer. The first algorithm offers a method to formally verify the existence of a solution, contrary to all other heuristics known to date. The second algorithm is a heuristic search that takes capacity constraints in account. Both algorithms are shown to be faster by orders of magnitude than existing solutions. Finally, we develop a new routing algorithm for wireless mobile ad hoc networks, adopting ideas from the Ant Colony Optimization metaheuristic. The routing scheme can adapt to network and traffic changes and uses multipath routing and an efficient local repair mechanism to improve failure resilience.
