Title: Mobility in Ad Hoc Wireless Networks: Friend or Foe?

Abstract

Ad hoc wireless networks are operated in multiple hops in which mobile nodes cooperate to maintain network connectivity. These networks perform various functions, including routing for. In this presentation, two opposing views of mobility in ad hoc wireless networks are presented. One view casts mobility as an undesirable feature. This view normally represents an ad hoc wireless network as a connected graph where path information needs to be maintained to ensure message delivery. Another view considers mobility as a desirable feature which can increase network capacity and even assist the routing process. We offer our views on these two approaches and discuss some recent discoveries regarding mobility-mitigation mechanisms, including buffer zones and view consistency.

Finally, we present several future applications of wireless networks.
