Abstract: Wireless computingis the delivery of computingas aservicerather than aproduct, whereby shared resources, software and information are provided to users over anetwork. Wireless computing entrusts services with a user's data, software and computation on a published Application Programming Interface (API) over a network. Wireless computing is defined in simplest terms as follows: A set of pooled computing resources, delivered over the web, powered by software. It is a form of computing that involves the interaction of several virtualized resources, meaning that many servers are connecting and sharing information that can expand and contract across servers depending on the amount of servers needed to manage the amount of traffic on various sites. Wireless allows the end users to use the application without installation and access their personal files at any computer with internet access. Apart from the advantages of wireless environment, security is the major issue. Due to the distributed nature, wireless environment is an easy target for intruders looking for the possible attacks to exploit. There are many advantages in wireless computing such as increased storage, highly automated, flexibility, mobility, etc. apart from these advantages the major issue in wireless environment is security. Due to the distributed nature of the wireless environment many users can access the wireless to utilize the service. So, there is a chance for an intruder or attacker to exploit an attack in the wireless environment. In order to address this issue in the wireless environment an Intrusion Detection System (IDS) is proposed based on the features of the mobile agent. The mobile agents are used to collect and analyze the data collected from wireless environment to identify attacks exploited by the intruders. The main objective of the proposed system is to detect the known and new attacks exploited by the intruders in the wireless environment.
