Routing protocols for vehicular ad hoc networks (VANETs) have attracted a lot of attention recently. Most of the researches emphasize on minimizing the end-to-end delay without paying attention to reducing the usage of radio. This paper focuses on delay-bounded routing, whose goal is to deliver messages to the destination within user-defined delay and to minimize the usage of radio because radi...

The spatiotemporal character of mobicast in sensor networks relates to obligation to deliver a message to all the nodes that will be present at time t in some geographic zone Z, where both the location and the shape of the delivery zone are the functions of time over some interval (tstart, tend). In this paper a learning automata based mobicast protocol for sensor networks to support applicatio...

We propose a localized address autoconfiguration (LaConf) scheme for wireless ad hoc networks. Address allocation information is maintained on the network border nodes, called addressing agents (AAs), which are locally identified by a geographic routing protocol GFG (Greedy-FACE-Greedy). When a node joins the network, it acquires an address from a neighboring AA (if any exists) by local communi...

Here we present performance evaluation of different routing protocols such as SIFT, GPSR and GOSR using different mobility models like Fluid Traffic Model (FTM), Intelligent Driver Model and Random Waypoint Model (RWM) with Intersection Management (IDM-IM). We present simulation results that demonstrate the importance of choosing a mobility model in the simulation of a Vehicular Network Protoco...

Wireless communication consumes a significant amount of energy in wireless networks. Most multi-hop wireless routing protocols are adopted from wired network routing protocols and use pre-selected single or multiple minimum cost paths to forward data packets. However unlike wired networks, a wireless network has unique characteristics such as unreliable wireless links and multiple receivers ass...

There has been a growing interest in the cooperative communication of power line and wireless dual-medium, due to promising transmission quality immense flexibility network. However, under condition hybrid fading impulsive noise, theoretical analysis two-way relaying with is difficult because lack closed analytical expressions. In this study, authors propose signal processing method based on Lo...

Mobile sinks can achieve load-balancing and energy-consumption balancing across the wireless sensor networks (WSNs). However, the frequent change of the paths between source nodes and the sinks caused by sink mobility introduces significant overhead in terms of energy and packet delays. To enhance network performance of WSNs with mobile sinks (MWSNs), we present an efficient routing strategy, w...

In this paper we investigate the use of ad-hoc routing algorithms for the exchange of data between vehicles. There are two main aspects that are of interest in this context: the specific characteristics of ad-hoc networks formed by vehicles and the applicability of existing ad-hoc routing schemes to networks that display these characteristics. In order to address both aspects we generate realis...

For the emerging wireless mesh networks with multiple radios and directional antennas, this paper first proposes a position-based deployment and routing strategy, and then gives a concrete approach under this strategy. The main idea of this strategy is to deploy the network in certain kind of geometric graph and then design a position-based routing protocol accordingly, so as to achieve efficie...
