Abstract
Wireless technology has become an essential part of this era’s human life and has the capability of connecting virtually to any place within the universe. A mesh network is a self healing wireless network, built through a number of distributed and redundant nodes to support variety of applications and provide reliability. Similarly, anycasting is an important service that might be used for a variety of applications. In this paper we have studied anycast routing in the wireless mesh networks and the anycast traffic from the gateway to the mesh network having multiple anycast groups. We have also studied the geocast traffic in which the packets reach to the group head via unicast traffic and then are broadcasted inside the group. Moreover, we have studied the intergroup communication between different anycast groups. The review of the related literature shows that no one has considered anycasting and geocasting from gateway to the mesh network while considering the multiple anycast groups and intergroup communication. The network is modeled, simulated and analyzed for its various parameters using OMNET++ simulator.

Summary
The basic aim of the wireless mesh networks (WMNs) is to guarantee the connectivity. WMNs are gaining popularity for its wide range of applications. They have a fixed infrastructure in the form of gateways and either mobile or fixed wireless mesh clients. Gateways provide the internet access to the wireless nodes This is the most common application of the wireless mesh networks. Video on demand and IP-TV are other interesting applications of a high speed wireless mesh networks Among all these applications group communication is an important paradigm to study. If there are various groups of the same category the anycast traffic will be forwarded to the hop towards the group head having larger calculated parameter (temperature field). The geocast technique presented in this paper is for WMNs and for the traffic generated by gateway to mesh clients based on the field base routing. The research work will consider multiple anycast groups, in the result the inter-group communication becomes possible
