摘 要
Ad hoc wireless networks are multi-hop networks in which mobile nodes cooperat
e to maintain network connectivity. These networks perform various functions i
ncluding routing. In this presentation, two opposing views of mobility in ad h
oc wireless networks are presented. One view casts mobility as an undesirable
feature. This view normally represents an ad hoc wireless network as a connect
ed graph where path information needs to be properly maintained to ensure mess
age delivery. Another view considers mobility as a desirable feature which can
increase network capacity and even assist the routing process. We offer our v
iews on these two approaches and discuss some recent discoveries regarding mob
ility-mitigation mechanisms, including buffer zones and view consistency. Fina
lly, we present several future applications of wireless networks.
