The unpredictable movement of the nodes in the mobile ad hoc network creates topological changes which demands adaptable routing. The on-demand routing protocol AODV gained a lot of attention from the researchers in the mobile communication era. The AODV routing protocol operates on some default parameters in a dynamic environment. In this paper, an attempt ...

Today internet has become an central part of the people lives. It has a great increasing user community in many fields from transactions in the banking to the online entertainments. There are many wireless technologies which are used for the communication process over the internet. But Wireless Mesh Networks (WMNs) have been proved much promising ...

Wireless communication is blooming along with Internet access from mobile devices which is an essential criterion for information access from anywhere, any time and any device. In this paper, review on various technologies like pervasive computing, mobile communication systems, selective dissemination of information, with location and device independent information interchange specification like XML (Extensible Markup ...

Orthogonal Frequency Division Multiplexing (OFDM) is a prominent technology for next generation high data rate communication systems. But there are several problem associated with design of OFDM system which needs to be addressed. High Peak to Average Power Ratio (PAPR) of OFDM system is one of the most important issues, which needs to be addressed. ...

Wireless ad hoc networks have received significant attention in recent years due to their easiness to setup and their potential applications in many domains. Such networks can be useful in situations where there is not enough time or resource to configure a wired network. The shared media used by wireless networks, grant exclusive rights for ...

In this paper, the authors examine Mobile Ad-hoc NETworks (MANETs) performance metrics which are mainly: the throughput, the energy consumption and the routing overhead. The reactive Ad-hoc On-demand Distance Vector (AODV) routing protocol was compared to the proactive Destination Sequenced Distance Vector DSDV according to the proposed performance metrics. The simulation was performed using the ...

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, the authors implement a Cross Layer based Detection and Authentication technique for Secure multi-path Routing (CLDASR). In the authentication method, when a source wants to ...

Basic characteristic of wireless networks that makes it vulnerable to attacks is its broadcast nature. Attacks are of various types that effect confidentiality and integrity of wireless network and in this paper, the authors are discussing about Jamming attacks. Jamming can stop or disrupt wireless transmission. It is interference, noise or collision at the receiver ...

Scheduling is a key Radio Resource Management (RRM) mechanism for realizing Quality of Service (QoS) requirements and optimizing system performance of Long Term Evolution (LTE) network. Scheduling is the process of dynamically allocating physical resources to User Equipments (UEs) based on scheduling algorithms implemented at the LTE base station. Various algorithms have been proposed by ...

The use of self-driving vehicles is becoming more and more significant in last few years. The fact that the vehicles are self-driving can lead to greater difficulties in identifying failure and anomalous states, since the operator cannot rely on its own body perceptions to identify failures. VANET turns every participating vehicle into wireless sensor nodes ...
