Recently, various applications for VANETs have been proposed and smart traffic violation ticketing is one of them. On the other hand, content-centric networking has been emerged into VANETs and named as VCCN. However, the existing applications in VANETs are not suitable for VCCN paradigm due to the dependency on a named “content” instead of a current host-centric approach. Thus, we still lack in the...
Stability and lifetime of Wireless Sensor Networks (WSNs) mainly depend on energy of each node in the network. Hence, it is necessary for a WSN to be energy efferent. There are different methods to preserve energy in WSNs and clustering is one of those methods. Clustering techniques divide whole network into small blocks, each having a managing node, called cluster head (CH) and rest of the nodes...
IEEE 802.15.4 standard is specifically designed for low Rate Wireless Personal Area Network (LR-WPAN) with low data rate and low power capabilities. Due to very low power consumption with duty cycle even less than 0.1, the standard is being widely applied in Wireless Sensor Networks applications. It operates in Beacon and Non Beacon enabled modes. During Beacon enabled mode, it has Contention Access...
In this paper, a framework for experimental parameters in which Packet Delivery Ratio (PDR), effect of link duration over End-to-End Delay (E2ED) and Normalized Routing Overhead (NRO) in terms of control packets is analyzed and modeled for Mobile Ad-Hoc NETworks (MANETs) and Vehicular Ad-Hoc NETworks (VANETs) with the assumption that nodes (vehicles) are sparsely moving in two different road. Moreover,...
This paper presents a survey of energy efficiency of Medium Access Control (MAC) protocols for Wireless Body Area Sensor Networks (WBASNs). We highlight the features of MAC protocols along with their advantages and limitations in context of WBASNs. Comparison of Low Power Listening (LPL), Scheduled Contention and Time Division Multiple Access (TDMA) is also elaborated. MAC protocols with respect to...
Several gateway selection schemes have been proposed that select gateway nodes based on single QoS metric, for instance link availability, link capacity etc. or multiple non-QoS metrics, such as the combination of gateway node speed, residual energy, and number of hops, for mobile ad hoc networks (MANETs). Each scheme just focuses to improve only single network performance such as network throughput,...
We propose a multipath routing protocol for mobile ad hoc networks (MANETs), which combines split multipath-dynamic source routing (SMP-DSR) and shortest multipath source routing (SMS) and changes those backup paths selection criteria. Our proposed scheme improves the transmission success rate and the energy consumption by considering two features. One of the feature is to construct the least hop...
Recently several weighted clustering algorithms have been proposed, however, to the best of our knowledge; there is none that propagates weights to other nodes without weight message for leader election, normalizes node parameters and considers neighboring node parameters to calculate node weights. In this paper, we propose an energy efficient and stable weight based clustering (EE-SWBC) algorithm...
This paper proposes an optimum mechanism to select appropriate gateway based on multiple node metrics: remaining energy, mobility, and number of hops, for interconnected mobile ad hoc network (MANET) with infrastructured network. To choose an optimum gateway node, we use the multiple criteria decision making (MCDM) method called simple additive weighting (SAW) to outrank the optimum gateway node....
