A survey on wireless ad hoc network: Issues and implementation

Wireless Ad hoc Network is the collection of wireless mobile nodes (devices) that are able to dynamically form a temporary network without the use of any existing network infrastructure or centralized administration. This paper discusses the roles of ad hoc networking in future wireless communications. In this paper we surveyed the different types of ad hoc networks such as isolated ad hoc networks with large and small sizes and integrated ad hoc networks for the mobile access networks. This paper gives various advantages and applications of ad hoc network. In addition, this paper also surveyed on ad hoc networks challenges in terms of Quality of Service (QoS), power control and security. This work discusses the implementation issues in ad hoc network and performance improvement by MIMO and cognitive radio techniques.
