Mobility and the absence of any fixed infrastructure make MANETs very attractive for mobility and rescue operations and time-critical applications. Considering mobility of the terminals routing is a key process for operation of MANETs. In this paper we analyze the performance of Optimized Link State Routing protocol in an indoor environment considering different scenarios for horizontal and vertical topologies. We evaluate the scenarios based on delay and jitter metrics. The experimental results show that for vertical topology the performance is affected more by mobility and number of hops in comparison with the horizontal topology. Keywords MANET OLSR Stairs Environment Obstacle Testbed 1 Introduction A Mobile Ad hoc Network MANET is a group of wireless mobile terminals which cooperate together by routing packets to each other on a temporary network. MANETs are attracting attention for their potential use in several fields such as collaborative computing and communications in indoor areas. Considering mobility of the terminals routing is a key process for operation of MANETs. Most of the work for MANETs has been done in simulation as .
