Message queue

Encapsulate persistence mechanisms in a small number of platform-dependent objects with platform-independent interfaces. Separate out technology-dependent infrastructure components that serve primarily to connect other components, such as message queues, transaction servers, ORBs, and databases. 

The above code assumes JMS is used as the messaging server. The register ) methods call the sendMessage method ) to submit the registration to a JMS message queue. Here we use a message queue rather than a message topic... 

Buffers are used to store multiple messages in message queues. Messages are stored in First In/First Out (FIFO) order. 

The request goes into an Input Message Queue, with priority based on the FIFO (first-in, first-out) method. 

Hence, provided that Wt = G (l) < I, which is the necessary and sufficient condition for stability of the periodic safety message queue [6], the PGF of can be calculated as follows [8, 9]... 

A website [11] is created in order to upload the ns-2 implementation of the VeMAC protocol, including the periodic and event-driven message queues, for interested researchers.
