Today, cellular networks, notably LTE, are used in substructure communications because of easeof launch, tranquil maintenance, the movable equipment, the communal accessed, and otherservices. LTE has superior improvement in efficiency, higher data rates, lower time lag, costsavings, capacity, and coverage. How to categorize BTS antennas and handover at the borderpoints are main consequence in these networks. there is possibility to set unessential handoverindoors. Also ability to eliminate unnecessary handovers and optimized the networks structure. Asa response, several scenarios, such as using the SOM neural network, the X-means clusteringalgorithm, ICA colonial competition algorithm , and other innovative and meta-innovativealgorithms are introduced. Setting up, testing, and evaluating need to a simulated environment. Inthis research, we tried to examine this type of the LTE network and the its Handover, by analyzethe tools’ feature and network simulation languages such as (NS-2, NS-3, OMNET ++), we canpresent the right choice. Then, we will examine the possibility of implementing LTE and Handoverscenarios in NS-3.
