ANEJOS: a Java based simulator for ad hoc networks

Ad hoc networks are multi-hop wireless networks where mobile devices commun icate using a shared, low power, low bandwidth channel without any wired in frastructure: each node acts also as a router of its neighbors. Ad hoc netw orks protocol design is still a new and growing research area: there curren tly is an IETF Working Group working on the definition of a standard for su ch networks. Various proposals are being evaluated and the need for a commo n comparison framework arises. This paper presents a simulator called ANEJO S (ad hoc networks Java simulator). The simulator is written in Java and is based on the SimJava tool and allows to be adapted to various routing prot ocols. It also allows considering other relevant aspects to ad hoc networks , like mobility patterns and traffic generation patterns. ANEJOS shared our models with other researchers through the internet, we can use Java applet s inside HTML pages containing the whole simulator. (C) 2001 Elsevier Scien ce B.V. All rights reserved.
