1. WHAT IS AD HOC NETWORK? With the advancement in radio technologies like Bluetooth, IEEE 802.11 or Hiperlan, a new concept of networking has emerged. This is known as ad hoc networking where potential mobile users arrive within the common perimeter of radio link and participate in setting up the network topology for communication. Nodes within ad hoc are(More)
Mobile Ad hoc Networks (MANETs) are subject to various kinds of attacks. Deploying security mechanisms is difficult due to inherent properties of ad hoc networks, such as the high dynamics of their topology, restricted bandwidth, and limited resources in end device. With such dynamicity in connectivity and limited resources it is not possible to deploy(More)
We present comparative analysis of MANET (Mobile of these protocols in high mobility environment like VANET may eventually cause many packets to drop. Route repairs and failures notification overheads increase significantly leading to low throughput and long delays. Such phenomenon is not suitable for Vehicular Ad hoc Networks (VANET) due to high mobility(More)
FANET is co-operative, reconfigurable, autonomous network of UAVs. The emerging technology of FANET has many applications in civilian and military field like search and rescue mission, surveillance, reconnaissance, monitoring etc. which create temporary mobile ad-hoc platform for communication and data collection. For such applications, main requirements(More)
Emerging standardization of Geo Mobile Radio (GMR-1) for satellite system is having strong resemblance to terrestrial GSM (Global System for Mobile communications) at the upper protocol layers and TCP (Transmission Control Protocol) is one of them. This space segment technology as well as terrestrial technology, is characterized by periodic variations in(More)
Localisation in wireless sensor network is the process of determining the geographical location of the sensor nodes. Conventional localization is space oriented which uses GPS (Global Positioning System) signal to obtain the location information of the nodes. But the GPS signals fail to work in indoor environments, the reason for which it becomes mandatory(More)
