Mobile Ad-hoc NETwork (MANET) is generally established in areas where infrastructural facilities such as base station, routers etc. do not exist or have been destroyed due to natural calamity. Due to their infrastructure-less nature they have several constrains such as bandwidth, computational capacity and battery power of each node. Power conservation is crucial to proper operations of MANET. Various researchers have provided several mechanisms to reduce the power consumption. One such mechanism is to take variable transmission range of nodes into account. This paper studies the impact of the same by designing a simulator in MATLAB. The authors observe a marked impact of variable transmission range on power saving.
