Mobile Ad-Hoc Networks Applications and Its Challenges
Communications and Network
Mobile Ad-Hoc Network (MANET) is an infrastructure less wireless network of autonomous collection of mobile nodes (Smart phones, Laptops, iPads, PDAs etc.). Network is self-configured to reconstruct its topology and routing table information for the exchange of data packets on the joining and leaving of each node on ad-hoc basis. This paper is based on the MANET applications and challenges. The researchers can get the overall concept of MANET as well as its applications and challenges. Keywords
... MANET, MANET Challenges and Applications N. Raza et al. 132 essential network functions in the nonappearance of immovable organization in a distributed manner. This type of network creates the way for various innovative and stimulating applications by functioning as an independent network or with multiple points of connection to cellular networks or the Internet . Routing of packets to destination is done by the cooperation of nodes of a MANET. The sending and receiving devices may be situated at a much higher distance as compared to transmission radius R, however, each network node can communicate only with nodes placed within its broadcast radius R. All the nodes in a multihop wireless ad-hoc network collaborate with one another to create a network in the absence of infrastructure such as access point or base station. In order to permit transmission among devices beyond the transmission range in MANET, the mobile devices require advancing data-packets for one another. The network devices can move freely and autonomously in any route. The nodes can detach and attach to the network haphazardly. Thus variations in link states of the node with other nodes are experienced by a node regularly. Challenges for routing protocols operating in MANET are eventually increased the movement in the ad-hoc network, changes in link states and other characteristics of wireless transmission such as attenuation, multipath propagation, interference etc. The challenges are boosted by the numerous sorts of nodes of restricted processing power and competences that may join the network  . Ultimate aim and objective of this research work is to analytically review routing protocols of MANET, simulate DSR, TORA and OLSR routing protocols by using simulator and compare the results under different scenarios like with Nodes Density of 25, 50 and 75 nodes, evaluate and analyze these routing protocols under the various environments by using some parameters like WLAN delay, WLAN throughput, WLAN network load, FTP traffic sent and received both by the nodes and server, routing traffic sent and received.
