Poisson arrival for MAC protocol

Hi all,

Good day.

I am trying to understand this piece of code which i modified on top of a code that i acquired from github.io. I am trying to simulate Slotted Aloha protocol.

Node = 10; % number of nodes TOTAL_SLOT_NUMBER = 10000; % simulation time lambda = 1; % average one arrival per time slot q = poissrnd(lambda,Node,TOTAL_SLOT_NUMBER); % generate poisson dist for N and simulation time

        for id=1:1:N % N is number of sensor nodes
            %%Poisson Arrival for every time slot
            is_arrival = rand;
            while is_arrival >=lambda*(exp(-lambda*q(index,t))) % is this correct? i modified this line.index denotes the current sensor node id. index = 1 is sensor node 1. t= current time slot
                % record the number of data frames in the queue
                buffered_number(id) = buffered_number(id) + 1; % array to store buffer data
                generated = generated + 1; % generates new data
                is_arrival = rand*is_arrival;
            end
        end

It is imperative that i understand this piece of code so that i can be sure that poisson arrival of packets are being simulated correctly.

Your comments are welcomed. Let me know if there is a simpler way of doing it.

Thank you.

Hi Remo,

I am interested in this ALOHA code, could you send me the full text of this?

Thank you
