Why traditional IP cant be used in mobile network?

Traditional IP protocols face challenges in mobile networks primarily due to their reliance on a stable, fixed IP address. Mobile devices frequently change locations and network connections, leading to issues with maintaining consistent connectivity and managing handovers between cells. Additionally, traditional IP lacks built-in mechanisms for handling the high mobility and varying bandwidth conditions typical of mobile environments, necessitating the use of more adaptive protocols like Mobile IP or newer architectures designed for mobility.
