The conventional mobile networks consists of macrocells or Evolved NodeB (eNB) which provide good coverage but reduces bandwidth available for a given area. The problem of coverage and lim- itation of bandwidth in a mobile network system is solved by using femtocells or Home Evolved NodeB (HeNB). In this thesis various handover scenarios have been considered for a LTE network having both femtocells (HeNB) and macrocells (eNB). Three handover scenarios: hand-in, hand-out and inter- femtocell and two dierent handover strategies: reactive and proactive handover are considered and analyzed. The mobility of the User Equipment (UE) has also been taken into consideration to achieve an optimal handover procedure. An algorithm has been proposed, which is used to dynamically decide upon the handover policy to be used based on the UE mobility and signal strength from the various available cells. The signaling and latency in handovers is studied using X2 interface between macrocells and femtocells. The proposed algorithm has been studied using the NS-3 simulator.
