Routing in adhoc networks is a challenge as nodes are mobile, and links are constantly created and broken. Present ondemand adhoc routing algorithms initiate route discovery after a path breaks, incurring significant cost to detect disconnection and establish a new route. Specifically, when a path is about to be broken, the source is warned of the likelihood of a disconnection. The source then ...

Mobile Adhoc Networks (MANET) is decentralized, self configuring, wireless network of mobile devices without using any infrastructure. MANET required dynamic routing to respond to the topological changes as nodes are dynamic in nature. Dynamic routing protocol such as Adhoc on demand distance vector routing (AODV) with Expanding Ring Search (ERS) is widely used technique to reduce energy consum...

Mobile Ad hoc Network (MANET) allows portable devices to establish communication independent of a central infrastructure. The wireless links in this network are highly error prone and can go down frequently due to mobility of nodes. Therefore, routing in MANET is a critical task due to highly dynamic environment. Efficient Routing Protocols will make MANET reliable. Protocols are of three kind ...

In recent years, mobile sensor networks (MSNs) have become a hot area of research, in which sensor nodes are mobile. The proper selection of a routing protocol in a MSN is very important because network performance is significantly influenced by the routing protocol. In this paper, the feasibility of the two routing protocols in MSNs is studied and discussed with respect to network performance....

Modeling complicated vehicular traffic behavior and analyzing effects on the communication performance of routing protocols taken by environmental factors have been a challenging task for the past several years. In this paper, we study the performance of multi-path routing protocol. Then, we investigate both multi-path and single-path routing protocol and analyze characteristics such as network...

An ad hoc network is a collection of wireless mobile nodes, frequently forming a network topology without the use of any existing network infrastructure or centralized administration. we compare the performance of the three prominent routing protocols for mobile ad hoc networks, Ad hoc On Demand Distance Vector (AODV), Destination Sequenced Distance Vector(DSDV) and Temporally Ordered Routing P...

In this article, the SAR (Security-Aware Routing) technology is applied in the AODV (Ad Hoc On-demand Distance Vector) routing protocol, the AODV is modified as viewed from security performances, the wireless Ad Hoc routing protocol with secure consciousness could be realized, and the secure routing protocol (SAR-AODV) is simulated in the OMNet++ simulation environment based on the platform of ...

We demonstrate an intuitive relation between conditional entropy and conditional expectation that is useful when one want to compare them as measurement tools to evaluate secrecy systems. In particular, we give a Security Property applicable to general vector variables in , using measurement based on vector quadratic distance, and we show that one can derive variables that can be measured with ...

We investigate the averaging problem in cosmology as the problem of introducing a distance between spaces. We first introduce the spectral distance, which is a measure of closeness between spaces defined in terms of the spectra of the Laplacian. Then we define SN , a space of all spaces equipped with the spectral distance. We argue that SN can be regarded as a metric space and that it also poss...

Node misbehavior due to selfish or malicious intention could significantly degrade the performance of MANET because most existing routing protocols in MANET are aiming at finding most efficiency path. To deal with misbehavior in MANET, an incentive mechanism should be integrated into routing decision-making. In this paper firstly we review existing techniques for secure routing, and then propos...
