A survey on short ad hoc network vaibhav v bhujade1,jagdish r yadav2,priti v ad hoc network is often local area network or other small area network formed by wireless devices in latin, ad hoc literally means for this, further meaning for this purpose only, and thus usually temporary the term has been applied to future office, home and personal area networks. A telecommunications system includes a public land mobile network for providing wireless service to users and a wireless local area network functioning outside the said plmn as a separate plmn an inter-plmn backbone interfaces the wlan to the plmn, and an interworking function is coupled to the wlan to provide seamless interactions.
The objective of this thesis is to study the integration of different technologies like wpan, wlan and gsm having different capabilities and protocol stacks to mobile ad hoc networks performance improvement issues relating to network configuration, human understandable naming mechanism and sophisticated location aided routing.
