Handover Mobile Wireless Communication Network Projects

Handover Mobile Wireless Communication Network Projects, enable the idea to balance the motion of the user devices. At first, the handover (i.e.) HO states that transfer the connected link from one network base station (BS) to another. To make clear, the ongoing call of a user disconnects due to mobility, and then it again connects with other nearby BS on the basis of specific metrics. 

Is it essential to perform HO? Do there exist many types of HO?

   Yes, HO is a basic need since the smartphones are handy and not at a position always. In simple, the HO is of two types, such as 1. Hard HO, and 2. Soft HO that defines HO in inter-cell and intra-cell. To this point, the hard and soft HO operates on the basis of BREAK-BEFORE-MAKE and MAKE-BEFORE-BREAK. Now that the first type will break the link and then connects while the second type will connect with new and then breaks the old link.  

Different Aspects of HO techniques

• Network controlled HO
• Mobile device-based HO
• And also, Mobility aid HO 

   In fact, there are Vertical HO (i.e.) VHO & Horizontal HO (i.e.) HOH. That is to say, the VHO handles different Radio Access Networks such as UMTS, WiFi Network Simulation Projects, and more, while the HOH handles only if the same network. In general, a HO is not a single step process; it requires to perform a set of the procedure as below.

Four Steps to be followed in HO

1. Handover Preparation. 
2. Request Handover to target BS or AP. 
3. Execute HO request and make a decision, then break the prior BS link.
4. Perform handover. 

   For a HO, it computes metrics that can be either on network or device. Then, this type of HO prediction studies on Handover Mobile Wireless Communication Network Projects. Later the intrasystem HO is of two such as X2 and S1, in which the interface differs. Whatever may be the HO, it is mandated, and so we list those metrics here.    

Criteria Evaluated for Handover in Wireless Networks

• Network related measures
• SNR, RSSI, and also RSRQ
• BER 
• Latency 
• PoAs 
• Terminal based metrics
• Distance and also Position 
• Moving velocity 
• Transmission power 
• Channel availability 
• User assisted 
• User profile
• User preference 
• Service-oriented 
• QoS and QoE
• Quality of traffic 

   In any case,Handover or Handoff must perform else it leads to packet loss, low QoS, delay, and so on. For instance, if a user lives stream video while traveling, then there occurs HO. If the HO is good, it results in the best video quality without buffering else; it happens in reverse so that we give some methods of HO down, which can result in better. 

Techniques in Handover Mobile Wireless Communication Network Projects 

• Decision-making algorithms (Weighted fuzzy, AHP, and so on)
• Reinforcement learning (Q-learning, SARSA, and etc.)
• Metaheuristic algorithms (PSO, GA, and many more)

   In wireless networks, handover plays a vital role in which the ping-pong effect will exist. In the long run, a ping-pong effect is that a mobile device is not in link with one AP but with both APs. As long as this extends, then it brings failure in HO. Hence by now, we deliver with some main metric underneath.  

Testing Performance Metrics

• Handover time 
• Ping-pong rate 
• Probability of HO failure
• HO success rate
• Number of HOs
• Number of failed HO
• User sum rate 

   Above all, we keep in touch with this field at all times. Hence it is familiar for us to work on any of your own concepts too. On the whole, you will get a good mobile communication simulation project.
