ABSTRACT
MAC protocols for wireless sensor networks employ periodic switch-
ing to low energy sleep state in order to enhance network lifetime.
During the sleep state, the sensors do not perform energy consum-
ing operations such as receiving and transmitting packets. During
the normal state, CSMA based multi-access mechanism is the MAC
protocol of choice in distributed, unsynchronized sensor networks.
The energy conserving mechanism has a two-fold effect on delay
in the network. On one hand it increases delay since many a times
