A Joint Local Short Scheduling Mechanism for a Successful MIMO-OFDM Communication System.

In recent days, the allocation of resources in a wireless communication system is one of the demanding and crucial task. Multi input multi output (MIMO)-Orthogonal frequency division multiplexing is the widely used communication system, in which scheduling the resource to the appropriate user equipment (UE) is quite a challenging process. To overcome this a different scheduling mechanisms are proposed in the traditional works for efficient resource allocation. But, it lacks with some limitations such as, increased error rate, inefficient allocation, increased load at tower, and increased interference. Thus, this paper objects to introduce a new optimization based scheduling mechanism, namely, Joint local shortest scheduling (JLSS) for a successful MIMO communication. Initially, the Rayleigh channel initialization and estimation processes are performed after creating the Cellular radio network with different number of users. Then, the features of the channel are extracted by implementing a beamforming feature extraction technique. Here, a Multi-channel bacterial foraging optimization algorithm (MC-BFOA) is implemented for selecting the most suitable channel for communication, due to its increased efficiency. Finally, the JLSS is employed to scheduling the resource to the user equipment (UE), in which three different mechanisms such as Primary channel bit allocation, Secondary channel bit allocation, and Extra channel bit allocation are used. Based on the priority level, the resource is allocated with the use of these mechanisms. During experimentation, the scheduling results of existing and proposed techniques are evaluated by employing different parameters. [ABSTRACT FROM AUTHOR]
