In wireless ad hoc networks, energy efficiency plays important role to improve the lifetime of network. Nodes in wireless ad hoc network are limited battery powered. Therefore, energy efficiency is of vital important in the wireless ad hoc network. Hence there is challenge to maximize the network lifetime. This paper presents a brief overview of wireless ad hoc network, causes of energy loss an...

Wireless Ad-hoc network is one of the most innovative network technologies which are carried out using multicasting applications in various domains. Partially Observable Markov Decision Process (POMDP) provided higher structural security but did not provide multicasting packets in the wireless ad-hoc network. Works conducted on Resource Biasing Approach attained multi casting efficiency by incr...

B ECAUSE the subject of this issue is wireless ad hoc networks, it would be beneficial to provide a definition of the phrase ad hoc as it is used in the context of mobile wireless networks. We have as a starting point the common definitions of this phrase, such as " for a specific purpose or occasion " or " for this case alone, " and many of us have served on at least one ad hoc committee. But ...

In this paper, we discuss security issues and their current solutions in the mobile ad hoc network. Ad hoc networks are a new wireless network for mobile hosts. Owe to the vulnerable nature of the mobile ad hoc network, there are many security threats that effected the development of wireless network. We evaluate the accessible in the mobile ad hoc networks and find out attacks than the convent...

A Wireless Ad hoc Network is a collection of wireless nodes forming a self-configuring network lacking of using any obtainable transportation. Since Wireless Ad Hoc Networks are not currently deployed on a large scale, research in this area is generally simulation based. Among other simulation parameters, the mobility model plays a significant role in determining the protocol performance with t...

Network coding technique increases wireless network communication efficiency. Wireless multihop relay network has been shown to achieve capacity gain over conventional single-hop wireless networks. Hybrid wireless relay networks integrate multihop ad hoc relay and infrastructure base stations to achieve better wireless network performance. Applying the promising network coding technique to hybr...

Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. In this article we present a study of secure ad hoc routing protocols for wireless Networks. ...

Wireless sensor ad-hoc network usually applied in a monitoring system like monitoring temperature, humidity or even any triggering inputs from a connected peripheral device. The approach of wireless ad hoc network for monitoring video data is under preliminary investigation and development because video streaming requires larger storage, quality channel, less jittering and low packet loss. The ...
