Dynamic Cooperative Multi-Cell Selection using Time Difference of Arrival in LTE network

In recent (4G) and next generation (5G) of wireless cellular networks it has been observed since 2020 that the applications are notably different from earlier days. The important areas which focus on improving the 5G networks are flexibility, capabilities, and efficiency. There is a requirement that support for various users, services, and applications. To accomplish the need of next generation wireless networks, the densification and multicell cooperation are the most important approaches. In the dense deployment cellular network, we need to study in-depth the components such as density of macrocells (eNBs), interference issue, transmission power and mode of eNBs such as active or idle. In addition to these issues, there is a need to address mobility management for Co-operative Multipoint (CoMP) operation in the heterogeneous networks. In dense network the User Equipments (UEs) may face problem of signal quality due to the limited resources at backhaul. Even though the users are stationary they may need to perform handover to another cell due to less signal strength received from the current access point. In these kinds of situations, the efficient way of performing handover becomes the soft handover or cooperative handover. In cooperative handover the UE is served by more than one base station. In dense network, UE faces the interference issue from multiple cells, which need to handle efficiently using cooperative mechanism. Hence in this paper we proposed the Dynamic Cell Selection mechanism to address the above-mentioned issues. To search nearby cells, we used the Time Difference of Arrival (TDOA) mechanism for computing the distance between source and receiver. Our proposed mechanism is "Dynamic Cooperative Multi-Cell Selection using Time Difference of Arrival in LTE network".
