Abstract:  An increasing number of machine-to-machine (M2M) devices are accessing upstream
of the cellular network, while the resource is limited. This paper analyzes the
resource allocation problem when M2M devices multiple access upstream with time division
multiple access (TDMA) or frequency division multiple access (FDMA). An algorithm
is proposed to allow sleep mode to dynamically allocate resource. By dropping a small
fraction of arrivals from the devices farther out near the cell edge, the base station can
increase its maximum load. While allowing dormancy and relating remaining energy with
sleep mode, both the base station centrally dynamically allocating resource and devices’
distributed opportunistic uploading can achieve a network lifetime longevity compared with
no sleep mode.

Key words: machine-to-machine (M2M), cellular network, multiple access, resource allocation, network lifetime
