| Abstract: | This paper presents several reasonable assumptions on mobile ad hoc network and introduces a discrete-time Markov chain(DTMC) model, called adhoc-{dt} model, Based on the adhoc-{dt}, the equilibrium distribution of the model can be obtained. And it calculates some important mobile ad hoc network parameters, such as the probability that a particular mobile host is in the vicinity of another mobile host, the average number of a mobile host's neighbors, the average flooding distance, etc. Also it proposes a specific definition method of the transition probability matrix and obtains the corresponding results. |
| Keywords: | Mobile ad hoc network Discrete-time Markov chain(DTMC) Equilibrium distribution Average flooding distance |
