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...

Intelligent Transportation Systems (ITS) has gain a lot of popularity due to much technological advancement in Vehicular Ad hoc Networks (VANETs). VANET provides safety and entertainment services to vehicle users. Therefore, constrained safety is a prominent feature for VANETs. Since the vehicular nodes typically moves fast than the nodes movement in other network such as Mobile Ad hoc Networks...

The performance of geographic routing protocols is impacted by physical voids and localization errors. Traversing voids is carried out by a complimentary algorithm, which requires high overhead and results in lower quality paths. Furthermore, localization errors lead to inefficient routes or even misrouting of packets. Accordingly, virtual coordinate systems (VCS) were proposed to be an alterna...

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...

Energy efficiency and reliability are widely understood to be one of the dominant considerations for Underwater Wireless Sensor Networks (UWSNs). In this paper, in order to maintain energy efficiency and reliability in a UWSN, Cuckoo Optimization Algorithm (COA) is adopted that is a combination of three techniques of geo-routing, multi-path routing, and Duty-Cycle mechanism. In the proposed alg...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...

Epidemic forwarding has been proposed as a forwarding technique to achieve opportunistic communication in Delay Tolerant Networks (DTNs). Even if this technique is well known and widely referred, one has to address several practical problems before using it. Unfortunately, while the literature on DTNs is full of new techniques, very little has been done in comparing them. In particular, while B...

In this paper, we propose an efficient Two-Phase geographic Greedy Forwarding (TPGF) routing algorithm for WMSNs. TPGF takes into account both the requirements of real time multimedia transmission and the realistic characteristics of WMSNs. It finds one shortest (near-shortest) path per execution and can be executed repeatedly to find more on-demand shortest (near-shortest) node-disjoint routin...

In recent days, vehicles usage and speed are highly increased that leads to an increase in energy consumption, delay, overhead the network. this paper, a novel trajectory is introduced achieve maximum reliability namely trust mobility-based evaluation for intelligent collaborative (TMIC)-UAVs assisted VANETs. Reactive multipath greedy routing protocol (RMGR) hybrid it combination of ad hoc on-d...
