| Research Abstract |
We consider an ad-hoc network on a straight road consisted by two pedestrian/terminal groups which move from right to left and from left to right according to independent Poisson processes, and analyze the distribution of continuation-time during which two standing terminals along the road can communicate with each other via moving terminals held by pedestrians. Compared with the case where the network is constituted by a one-way pedestrian /terminal group, the continuation time is usually short. However, sometimes it is fairly long. By showing simulation results, we discuss about these features. Moreover, we discuss asymptotic behavior of the continuation time when terminal density, lambda, or the distance between two standing terminals becomes large.
