Windows end-users and Internet routing technology have both become more frequent targets of intruder activity. The control mechanisms for DDoS attack networks are changing to make greater use of Internet Relay Chat (IRC) technology. The impacts of DoS attacks are causing greater collateral damage‚ and widespread automated propagation itself has become a vehicle for causing denial of service. While DoS

line 1. INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in
