Abstract—As the traditional resources (frequency, time, space, etc.)are efﬁciently utilized,it becomes more challenging to satisfy the ever-lasting capacity-growing and users-boosting demand in wireless networks. Orbital angular momentum is a special method to overcome the interference and enhance the channel capacity of wireless communication. The feasibility of creating reliable communications links impervious to threats and external attacks by exploiting light (OAM) has already been recognized by Defense Advanced Research Projects Agency. The channel capacity of the near-end and far-end user for OAM based transmission is improved with the use of SWIPT protocol. For secure and reliable communication in military area proposed a method considering with simultaneous wireless information and power transfer (SWIPT) protocol with OAM. The performance result shows that the diversity achieved by the method is secured and reliable as expected.
