|Abstract: ||Mobile ad hoc networks are characterized by having nodes that are
cooperative and communicate without any kind of infrastructure.
The mobility and multihop capability of these
networks leads the network topology to change rapidly and
unpredictably; this aspect must be incorporated in effective models to describe the dynamics of multihop paths.\newline
When modeling the duration of multihop paths, a great part of the literature assumes that the links of multihop paths behave independently. This simplifies the modeling and reduces the complexity of computations. However, each link shares a common node with each of its neighbor links, turning the independent link assumption ge-nerally not valid.
In this paper, we use a piecewise deterministic Markov model that characterizes the random behaviour of a multihop path not assuming independent links. We obtain the mean path duration of multihop paths and compare the results for the used model with the ones obtained by assuming independent links.
results illustrate that independent link approximation
results underestimate the mean path duration, with the most significant differences being observed with low node mobility and higher path durations.|
