Mobility Requirements in Tactical IP Networks : A Study of Available Techniques and Future Challenges

This report studies the requirements of IP mobility in tactical networks. Whatchallenges are there and how can they be dealt with. Different mobility aspects arestudied and the challenges for these are presented and discussed. Within the reportthree different protocols namely Session Initiation Protocol (SIP), Mobile IP (MIP) andHost Identity Protocol (HIP) are evaluated and different implementations of theseprotocols are studied. A combination of MIP and SIP is suggested to solve mobilitychallenges in a tactical IP network that consists of multiple nodes with differentproperties. Currently unsolved challenges are discussed and a proposal for furtherwork is presented
