The abstract Data delivery in vehicular ad hoc networks (VANETs) has become one of the most challenging problems due to the rapid movement of vehicles and their bounded communication ranges. How to more efficiently transmit the sensing data about the region of interest to AP is discussed in this paper. Previous work hasn’t distinguished node types to forward data packet commonly, the delivery r...

Providing reliable and efficient communication under fading channels is one of the major technical challenges in wireless sensor networks (WSNs), especially in industrial WSNs (IWSNs) with dynamic and harsh environments. Reliable Reactive Routing Enhancement (R3E) to increase the resilience to link dynamics for WSNs/IWSNs. R3E is designed to enhance existing reactive routing protocols to provid...

Existing reliable-oriented routing protocols computes link reliability based on the packet reception ratio and neglects impact of various parameters such as noise, shadowing, battery-lifespan, uncertainty and geographic locations. In this paper, we propose a Link Reliable Reactive Routing (LR3) protocol for WSNs to accomplish reliable and resilience to out-of-order transmission and path diversi...

Optimized Link State Routing (OLSR) is a in a popular proactive routing protocol for providing peer-to-peer transmissions in mobile ad hoc networks (MANETs). Since sensitive data are communicated in MANET, security remains a major issue. In this paper, we propose a trust based Multipoint Relay (MPR) selection algorithm for defending a specific type of denial-of-service (DOS) attack called node ...

Advances in wireless technology and portable computing along with demands for greater user mobility have provided a major movement towards development of ad-hoc networks. The main Method for evaluating the performance of MANET’s is simulation. An extensive simulation is performed using NS-2 simulator and end to end delay, packet delivery ratio, packet loss ratio, throughput and jitter for React...

In this paper we presents a method for handling multiple metrics and different network parameters simultaneously to analyze the loss factor of routing protocols in mobile ad hoc network(MANET) environments. We have used Taguchi’ loss function to determine the best parameters giving maximum throughput, packet delivery ratio (PDR), average delay, DROP and routing over head simultaneously for AODV...

In MANETs, providing the security to the network from the routing attacks like black hole and gray hole is a big challenge. To resolve the above issues, in this paper we implement a cross layer based detection and authentication technique for secure multipath routing (CLDASR). In the authentication method, when a source wants to send a data packet or a RREQ packet, it generates a hash value als...

Wireless technology has advanced to be become a vital part of our lives starting from mobile communication to health care departments. The main purpose of this research is to analyse and design efficient transmission control mechanisms for handling critical and non-critical data. In most of the existing literature works of WBAN, adaptive and reliable data transmission is handled individually. T...
