(RI-MAC), that uses receiver-initiated data transmission in order to efficiently and effectively operate over a wide range of traffic loads. RI-MAC attempts to minimize the time a sender and its intended receiver occupy the wireless medium to find a rendezvous time for exchanging data, while still

Initiated-Medium Access Control (RI-MAC) protocol. EMBA comprises two techniques for asynchronous mode broadcast of messages namely the forwarder’s guidance and the overhearing of broadcast messages and ACKs. Receiver initiated MAC broadcast for sparse and dense networks attempts to minimize

kinds of problems. One such problem is deafness. Deafness is caused when a transmitter repeatedly attempts to communicate with its intended receiver, but it fails because the receiver has its beam pointed towards a direction away from the transmitter. This paper proposes RI-DMAC (Receiver

-fore that the phospholipids play some fundamental role in the structural make-up and t’he vital activity of the cell. In this review an attempt has been made to outline the present state of our knowledge concerning the physiological behavior of the phospholipids and t!he functions which they perform. The discussion

is used. We introduce a low-power pseudo-random frequency-hopping MAC protocol which is specifically characterized as a duty cycled asynchronous sender-initiated LPL style protocol. We illustrate two flavors of the protocol; one that does not use any dedicated channel and another which allows dedicated
