International Journal of Distributed Sensor Networks, 2015 We propose and analyse a medium access control (MAC) protocol for low energy critical infrastructure monitoring (LECIM) networks. As the packet drop probability plays crucial role in LECIM applications, we propose framed slotted aloha based MAC for LECIM

On the optimal configuration of framed slotted ALOHA [PDF]
EURASIP Journal on Wireless Communications and Networking, 2016 The primary task of RFID readers is to identify multiple objects as quickly and reliably as possible with minimal power consumption and computation. One issue addressed in this study is the manner in which RFID systems adopting the framed slotted ALOHA (FSA) protocol should be configured so that the minimum identification delay can be achieved with a ...

Modeling and Analysis of Slotted ALOHA Systems With Energy Harvesting Nodes and Retry Limit
IEEE Access, 2018 We analyze the performance of slotted ALOHA systems with energy harvesting nodes and the retry limit by developing a node-centric two-dimensional discrete-time Markov chain (DTMC) model.

Analysis of the Slotted Aloha System with Multiple Accessible Rates
, 2007 過去的隨機存取（random access）假設每個使用者的接收速率相等，換言之，每一位使用者在相同時間內接收到相同數目的資料封包。然而在無線通訊的環境下，距離的因素會導致嚴重的衰減，包括fading及loss效應，因此不同距離的使用者能可靠地接收到資料的接收速率並不相同，這和過去研究的假設並不一樣。在這篇論文中，以多重傳輸速率下的slotted Aloha系統做為研究隨機存取系統多重傳輸速率性質的第一步。 本文探討當slotted Aloha中的使用者有不同的傳送機率時 ...

Stochastic Analysis of Non-slotted Aloha in Wireless Ad-Hoc Networks [PDF]
, 2010 accepted for IEEE Infocom 2010International audienceIn this paper we propose two analytically tractable stochastic models of non-slotted Aloha for Mobile Ad-hoc NETworks (MANETs): one model assumes a static pattern of nodes while the other assumes that ...

Channel throughput of slotted ALOHA in a Nakagami fadingenvironment [PDF]
, 1997 Slotted ALOHA is widely used in local wireless communications as a multiple access protocol. In addition, it is also used as a component in many reservation protocols. In this paper, the channel throughput of the slotted ALOHA protocol is evaluated for a
